A mint mark is a letter, symbol or an inscription on a coin indicating the mint where the coin was produced. It is distinct from a mintmaster mark, the mark of the mintmaster.

History

[edit]

Mint marks were first developed to locate a problem. If a coin was underweight, or overweight, the mint mark would immediately tell where the coin was minted, and the problem could be located and fixed. Another problem which could occur would be a dishonest mint official debasing the coin, or putting less precious metal in the coin than specified. The first mint marks, called "Magistrate Marks" were developed by the Greeks, and named the Magistrate in charge of producing that coin. Debasing a coin, or otherwise tampering with it, was a very serious crime, often punishable by death in many civilizations. For example, in 1649, the directors of the Spanish colonial American Mint at Potosí, in what is today Bolivia, were condemned to death for seriously debasing the coinage. The initials of the assayer as well as the mint mark were immediate identifiers when the coins were inspected.

In some cases the symbols found in the field of ancient Greek coins indicated mints, not magistrates. Mints in territories conquered by Alexander the Great struck coins with the types he used in Macedon but marked with a local symbol.[1] For example, Rhodes struck coins with Alexander's types marked with a rose, a local symbol previously used on its own coins.[2]

A reform of Diocletian made mint marks a regular feature of ancient Roman coinage. These mint marks were placed at the bottom of the reverse of the coin and contained three parts. The first part indicates that this was a coin with either SM for Sacra Moneta, M for Moneta, or P for Pecunia. The second part was an abbreviation of the name of the mint such as ROM for Rome or LON for London. The final part indicated the workshop within the mint.[3] The reform of Anastasius, which is the traditional dividing point between the coinage of the Roman and the Later Roman (a.k.a. Byzantine) empires, replaced the mint marks on gold coins by the inscription CONOB, meaning the pure standard of Constantinople, which was used by a variety of mints. Mint marks continued on copper coinage until the second half of the seventh century, however.[4]

Mint names began to appear on French coins under Pepin and became mandatory under Charlemagne.[5] In 1389, Charles IV adopted a system called Secret Points. This scheme placed a dot under the first letter of the legend on coins of Crémieu, under the second letter for Romans, up to the twenty-second letter for Bourges.[6] In the fifteenth century letters or symbols placed at the end of the legend indicating the mint were used in addition to Secret Points.[7] In 1540, Francis I discontinued Secret Points in favor of a system of letters; A for Paris, B for Rouen, …, Z for Lyon; in the field.[8] He also made it the rule for mint-masters to place their personal marks on coins, as they had done with increasing frequency since the coinage of Louis XI. This was one of the few royal practices continued by the Republic of France.[9] The mint letters continued until 1898 (briefly revived in 1914 and from 1942 to 1958) and the mint-masters marks, supplemented by the mark of the Chief Engraver, are still used.[10]

Some Medieval English coins used mint names .[11] When William III retired hammered coinage, branch mints which helped strike machine made coins to replace it put their initials below his bust.[12] The Royal Mint established branches to coin sovereigns near the sources of gold. These issues show the initials of Sydney, Melbourne, Victoria, and Perth Australia as well as Canada, South Africa, and India.[13] The privately owned Soho Mint obtained a contract to strike royal copper coins with steam presses and put its name on these coins and on coins it minted for other countries. When it closed, Ralph Heaton acquired its equipment, founded the Birmingham Mint, and put his H mint mark on coins of Canada, among others.

Spanish Milled Dollar with Mexico City Mint Mark.

The Spanish Empire introduced mint marks to the New World when they authorized Mexico City to open a mint on 11 May 1535. The Spanish Empire established mints throughout its American territories, each with their own mint mark. After its revolution, Mexico continued to use its colonial Mo monogram mint mark shown on either side of the date in the Spanish Milled Dollar. The United States of America established mints in Charlotte, North Carolina and Dahlonega, Georgia in 1838 after the Georgia Gold Rush and put its first mint marks on the gold coins struck there.[14] Like other countries, the United States has since placed mint marks not only on its own coins but also those of its territories, such as the Philippines, and other countries for which it has contracts to strike coins, such as Fiji.

Mint marks in numismatics

[edit]

In the 19th century, numismatists (coin collectors) did not generally collect coins according to mint mark; rather, they attempted to obtain date sets of coins. A turnaround began after 1893, when A. G. Heaton's "A Treatise on Coinage of the United States Branch Mints" was published. Heaton cited example after example of mint-marked coins that were much scarcer than Philadelphia products and that should bring high premiums. When the United States abandoned silver coinage in 1964, mint marks were removed from the new copper-nickel coins in the belief that it would reduce the removal of coins from circulation by collectors. The silver coins quickly disappeared from circulation, and it was feared that if collectors saved too many of the new coins, there would be a serious shortage of coinage. Mint marks were returned to United States coins in 1968.

United States Mint Marks

[edit]

The current mint marks on United States coinage are P, D, S, and W for the four currently operating U.S. Mints. The letter P is used for the Philadelphia Mint, D for the Denver Mint, S for the San Francisco Mint, and W for the West Point Mint.

There have been nine official United States Mints. The first U.S. Mint was in Philadelphia, which began coin production with large cents and the half cents of pure copper in early 1793. Other U.S. Mints, prior to the twentieth century, were considered "branch mints."

United States mint marks were originally used to distinguish coins not made in Philadelphia. The eight mint marks used to distinguish coins not minted in Philadelphia are as follows, listed chronologically with date of first coinage production:

The West Point Mint began coin production to ease the shortage of quarters and other minor coinage; this facility bore no mint mark. Thus, West Point coins could not be distinguished from those made at the Philadelphia Mint. The West Point "W" mint mark was first used on the $10 gold coins commemorating the 1984 Olympic games in Los Angeles.

Most Philadelphia Mint coins from earlier than 1980 were unmarked with the notable exceptions being wartime nickels (1942–1945) and Susan B. Anthony dollars (1979–1999). The "P" mint mark was first used on the Susan B. Anthony Dollars starting 1979.

From 1980 until 2017, the Lincoln cent was the only coin that did not always have a mint mark, using a "D" when struck in Denver but lacking a "P" when ostensibly struck at the Philadelphia mint. This practice allowed the additional minting of coins at the San Francisco mint ("S") and West Point mint ("W") without the use of their respective mint marks to address circulating coinage needs without the concern of creating scarce varieties that would be plucked from circulation by collectors. In the single year of 2017 the Philadelphia "P" was added to the Lincoln cent to celebrate 225 years of Philadelphia Mint service.[15]

Generally 21st century coins with an "S" or "W" do not circulate, being mostly produced as bullion, commemorative, proof coinage or other "collector coinage" sold by the U.S. Mint to either authorized bullion wholesalers or directly to collectors. There was also an exception, the 2019-W quarter made for circulation. Only 2 million were made for each design. The West Point Mint continues to make "W" quarters intended for circulation. This is called "The Great American Coin Hunt." The "S" mint mark were also used for circulated coins until 1980.

Other countries

[edit]

Although the US and several other countries use the initial letter of the city for its mint marks, this practice is not universal. For instance, Germany used A for Berlin, D for Munich, E for Muldenhutten, F for Stuttgart, G for Karlsruhe and J for Hamburg. When Spain adopted decimal coinage in 1848, it used stars with different numbers of points as mint marks. Madrid used six pointed stars, Barcelona used eight pointed stars, and so on. After the revolution of 1868, small dates were placed in these stars.[16] The small dates indicated the year the coin was struck, as opposed to the large date on the coin which was the year it was authorized.[17]

Many mints of the world commonly use a Privy mark, which is a symbol unique to each mint. The Royal Canadian Mint commonly uses a maple leaf privy mark. Segovia, Spain used an aqueduct, a local landmark, before it switched over to the star system in 1868. The private mint of the French Coinage Society Poissy Branch used a thunderbolt mint mark on coins of France, its colonies, Romania and other countries.[18]

Privy mark (left) and mint mark on a Dutch coin. The mint mark is that of the mint of Utrecht. Since 1830 (with an interruption in 1941–1945) this mark is pressed on all Dutch coins.

Many Islamic coins bear an inscription telling which mint produced the coin. This inscription is often the name of the city where the coin was minted spelled out in Arabic script.

Several euro coins have mint marks of their respective Mint. See Identifying marks on euro coins for more information.

Mint mark

View on Grokipedia
from Grokipedia
A mint mark is a small letter, symbol, or inscription stamped on a coin or medal to indicate the specific mint facility where it was produced. These marks have been used since ancient times to assign responsibility for coin quality, particularly in eras when precious metals were involved, and they play a crucial role in numismatics by helping collectors identify a coin's origin, rarity, and potential value. The practice of mint marking originated in antiquity, with the earliest known example appearing on a silver didrachm struck in around 269 BC, though Greek coins prior to that often included city names for similar identification purposes. During the , mint marks proliferated as European monarchies operated multiple mints and employed various moneyers, using symbols or letters to ensure accountability and distinguish strikes from different locations—such as France's 1540 , which assigned alphabetical marks like "A" for the Mint. By the , countries like managed dozens of mints, each with unique identifiers, while coins such as the bore marks like "SF" despite being produced at various global facilities including and . In the United States, mint marks were first introduced in 1838 on gold coins produced at branch mints in Charlotte (C), Dahlonega (D), and New Orleans (O), following the Coinage Act of 1835 that established these facilities; Philadelphia coins initially bore no mark as the primary mint. The "P" mark for debuted in 1942 on Jefferson nickels due to wartime silver content changes and has since appeared on various denominations, while marks were temporarily omitted from 1965 to 1967 under the to combat counterfeiting amid silver shortages, before being restored in 1968. Today, active U.S. mint marks include "P" (), "D" (), "S" (, primarily for proofs), and "W" (West Point, used sparingly on circulating coins like select in 2019); these distinctions are essential for collectors, as low-mintage examples from specific mints often command premiums based on scarcity and historical context.

Definition and Purpose

Definition

A mint mark is a small letter, , or design stamped on a coin or indicating the specific mint facility where it was produced. These marks serve as official identifiers applied during the minting process to denote the originating production site, distinguishing them from other features on numismatic items. Common formats of mint marks include letters, such as "D" for the in the United States, which has been used since to identify coins struck there. Symbols have also been used, particularly in historical contexts, such as stars, crescents, or branches on ancient Roman coinage to signify specific workshops or facilities within larger mint operations. Mint marks differ from die varieties, which arise from unintentional modifications or differences in the die during preparation, such as doubled , and from countermarks, which are supplementary stamps applied post-minting by secondary authorities for purposes like or . Unlike these, mint marks are deliberate and standardized indicators of the production location. They can appear in various styles, including incuse marks that are indented or recessed into the coin's surface for a contrasting effect, versus raised marks that protrude in , as determined by the mint's striking technique.

Functions

Mint marks serve primarily as a mechanism for quality control and accountability in coin production. By identifying the specific mint facility responsible for striking a coin, these marks enable authorities to trace production issues, such as deviations in weight, composition, or finish, back to their source. For instance, during eras when coins contained precious metals, commissions evaluated samples from each mint to ensure adherence to standards, holding the facility accountable for any substandard output. This system promotes consistency across multiple production sites and facilitates corrective measures if defects arise. In terms of distribution and legal purposes, mint marks assist governments in monitoring coin output to inform , combat counterfeiting, and comply with regulations. They allow central banks and treasuries to track the volume and flow of coins from individual mints into circulation, supporting decisions on monetary supply. Additionally, by denoting official production origins, mint marks enhance anti-counterfeiting efforts, as authentic marks verify legitimacy and reveal fakes that mismatch historical styles or placements specific to each facility. This traceability also aids in regulatory oversight for cross-border exchanges, ensuring coins meet jurisdictional standards. Mint marks fulfill an informational role by informing users about a coin's origin, which can highlight regional variations in metal content or design standards, particularly in historical contexts where mints operated under differing local conditions. This knowledge supports practical use in and exchange, as origin details can influence perceived value or acceptability in specific markets. In modern coinage, mint marks have evolved to denote editions or commemorative series, helping manage collector demand and distinguish special releases from standard circulation coins. For example, the "W" mint mark on select U.S. indicated West Point production for a limited run, boosting without altering core circulating output.

Historical Development

Origins in Ancient Coinage

The origins of mint marks trace back to ancient coinage systems, where symbols and inscriptions emerged to identify issuing authorities, ensure , and facilitate trade across decentralized economies. While 5th century BCE Greek city-states incorporated distinctive emblems on their silver coins—such as the owl on Athenian tetradrachms or the sea turtle on Aeginan didrachms—to denote the civic origin and affirm legitimacy among over 1,000 independent poleis, these were primarily civic identifiers rather than facility-specific mint marks. The formalized practice of mint marks, as small symbols or letters indicating the production facility, began with the around 269 BC on a silver didrachm struck in . The refined this tradition starting in the 3rd century BCE, evolving from simple symbols to more explicit identifiers tied to officials and workshops. Early Republican bronze aes grave and later silver denarii occasionally bore control marks like monograms or motifs to indicate the tresviri monetales—the s overseeing coin production—and specific workshops within or provincial facilities. By the mid-2nd century BCE, these marks became more formalized, incorporating abbreviated names, initials, or symbols such as anchors or caducei to denote the responsible , as seen on issues from the 150s BCE onward; this system helped track accountability amid expanding imperial mints in regions like and . Under the , from the 1st century CE, provincial mints extended this practice, using Greek letters or Latin abbreviations to specify locations like or Antioch, ensuring traceability in a vast currency network. In parallel, the (206 BCE–220 CE) introduced standardized inscriptions on Chinese cash coins, marking the rise of imperial mint control in East Asia. The iconic Wu Zhu (five zhu) design, initiated around 118 BCE under Emperor Wu, featured raised characters on the obverse denoting the coin's weight and value, produced at state-run mints in and other imperial centers to unify the economy post-Qin fragmentation. While not typically location-specific like later Roman or European mint marks, these uniform inscriptions—struck in massive quantities estimated in the tens of billions over centuries—signified centralized Han authority, distinguishing official issues from forgeries and supporting taxation and trade along the . Rare variants included additional characters for eras or workshops, foreshadowing later mint-specific notations. Elsewhere, ancient Indian from around 600 BCE featured symbols punched by authorities or guilds to indicate weight and authenticity, serving a similar identificatory role in trade networks across the subcontinent. In early medieval and the Islamic world following the Roman collapse around 500 CE, coinage adapted these practices to fragmented polities, using symbols and letters to assert local or caliphal sovereignty through the . Merovingian and Carolingian rulers revived minting at feudal workshops, employing crosses, lions, or initial letters (e.g., PAR for ) on silver deniers to identify regional authorities like those in or , aiding in the decentralization of post-Roman economies. Concurrently, Islamic caliphates under the Umayyads (661–750 CE) transitioned from imitative Byzantine and Sasanian designs to reformed dirhams and dinars bearing inscriptions with mint names (e.g., DIM for ) and dates, starting around 696 CE at facilities across , , and ; these marks, often in script, propagated caliphal unity while accommodating provincial variations. By the Abbasid era (750–1258 CE), such notations standardized across an empire spanning from to Persia, with symbols like stars or annulets supplementing textual identifiers for in gold and silver issues.

Evolution in the Modern Era

The expansion of European colonial empires in the 16th to 18th centuries prompted the establishment of overseas mints, where mint marks served to authenticate local production and distinguish coins from metropolitan issues. led this development, opening the mint in present-day in 1574 to process vast silver deposits from the mountain, marking coins with the letter "P" alongside assayer initials to identify origin and ensure quality control amid widespread counterfeiting concerns. These marks facilitated trade across the and global markets, as Potosí output dominated world silver supply, with similar systems in (mark "Mo") and (mark "L (I)") standardizing identification for multiple facilities. In , emerging national mint networks adopted letter-based standardization; for instance, France's 1540 monetary reform assigned alphabetical marks to over 20 provincial mints, such as "A" for and "AM" for , under royal oversight to regulate debasement and circulation. The 19th century's accelerated minting capacity and prompted formalized branch systems, with mint marks evolving into essential tools for accountability in expanding national economies. , the created the as the sole facility, but rapid gold and silver discoveries necessitated branches established by the Coinage Act of 1835: Charlotte ("C" mark, first used 1838), Dahlonega ("D", 1838), and New Orleans ("O", 1838), to track production and prevent fraud. Britain, during the (1837–1901), centralized coinage at the Royal Mint (relocated to in 1810) but extended imperial control through overseas branches, introducing marks like "S" for (1855) and "M" for (1872) on gold sovereigns to monitor output from antipodean facilities amid empire-wide gold rushes. These developments reflected broader mechanization, such as steam-powered presses, which enabled consistent mark placement and higher volumes, contrasting earlier hand-struck variability. Post-World War II reconstruction and in the fostered international mint collaborations and diversified symbols, adapting mint marks to global economic demands. The Royal Canadian Mint, operational since 1908, used a "C" mark on sovereigns struck at from 1908 to 1919 to distinguish them from British issues, symbolizing early national autonomy within networks. Economic upheavals influenced practices, as seen in the U.S. of 1933, which recalled coins and suspended their minting for circulation until after 1934 (limited to proofs thereafter), effectively pausing mint mark usage on denominations like the $20 while continuing it on silver issues from facilities such as ("D"). This shift underscored mint marks' role in regulatory compliance during crises, with global mints similarly adjusting outputs to postwar currencies. In the contemporary era, mint mark usage endures despite advances in digital minting technologies, balancing tradition with modern traceability needs. and laser etching have streamlined production, allowing precise mark integration, yet physical symbols remain prominent for historical continuity and numismatic appeal; for instance, euro coins launched in 2002 incorporate national mint marks (e.g., Germany's "A" for , "D" for ) on the national obverse side to identify issuing facilities across the . While serial numbering and blockchain-like digital ledgers enhance anti-counterfeiting in high-security issues, reducing some reliance on visible marks for bulk tracking, their retention on circulation coins preserves collector interest and jurisdictional transparency in an increasingly digitized global economy.

Role in Numismatics

Identification and Authentication

Mint marks are small symbols or letters stamped on coins to indicate the mint of origin, and their placement varies depending on the coin's , denomination, and historical period. Commonly, they appear on the obverse or reverse fields, along the rims, or positioned below the date, with early examples often featuring subtle incused designs while modern ones use more prominent raised lettering for clarity. For instance, on coins, mint marks were traditionally located on the reverse side until , when they shifted to the obverse for most denominations to facilitate easier identification during production and circulation. Interpreting mint marks requires reference to standardized catalogs that decode their meanings and . In numismatic practice, guides such as (commonly known as the Red Book), published by Whitman, provide detailed explanations of symbols, such as "S" denoting the , "D" for , "P" for , and "W" for West Point, along with variations in style and positioning across eras. These resources enable collectors to a coin's mark against documented production details, ensuring accurate cataloging without ambiguity from similar-looking symbols in different jurisdictions. In authentication, mint marks play a critical role by allowing verification against known mint outputs, helping to identify counterfeits or alterations where the mark's style, size, or placement deviates from official specifications. Genuine marks must align with era-specific designs—such as the distinct styles used by the U.S. Mint in the 19th versus 20th centuries—and integrate seamlessly with other security features like edge lettering or to confirm overall authenticity. Professional services like Numismatic Guaranty Corporation (NGC) examine these elements alongside composition tests to detect fakes, rejecting for coins with mismatched or fabricated marks. Numismatists employ various tools and methods to verify mint marks, starting with magnification devices such as 7x to 10x loupes or digital microscopes, which reveal fine details like strike quality and positioning invisible to the . Databases from grading services, including the PCGS Population Report and NGC , offer searchable records of certified coins by mint mark, date, and grade, allowing users to compare a specimen against verified populations for consistency. Additionally, historical records from the U.S. Mint's archives provide production logs and annual reports to corroborate mark authenticity against documented mintages and design changes.

Impact on Collecting and Valuation

Mint marks play a pivotal role in numismatic valuation by signaling production specifics that often determine rarity and desirability among collectors. Coins from facilities with limited output, such as the 1916-D with a mintage of only 264,200 pieces, exhibit heightened scarcity compared to higher-volume issues from the same year, leading to premiums that can exceed tenfold in auctions for well-preserved specimens. This supply-demand imbalance underscores how mint marks differentiate subtypes, with low-mintage examples routinely achieving values from $1,000 in circulated grades to over $30,000 in uncirculated condition. Collector strategies frequently revolve around assembling comprehensive sets that include all relevant mint marks for a given series, such as pursuing (P), (D), and (S) variants in Lincoln cents to fulfill date-and-mint-mark objectives. This methodical approach not only heightens the challenge and satisfaction of the hobby but also aligns with grading standards that classify coins by these distinctions, encouraging targeted acquisitions to complete registries or personal portfolios. In auction markets, mint marks amplify premiums through their association with unique varieties and errors, as seen in the 1937-D Three-Legged , where die wear at the facility created a distinctive missing foreleg, propelling values to $105,000 for top-graded examples due to the error's exclusivity to that mint. Broader economic trends, including rising investor participation during periods of market optimism, further escalate these dynamics, with rare mint mark coins often outperforming common issues in sales records. The influence extends to communal aspects of , where mint marks facilitate set-building initiatives within groups like the , promoting and exchange among members seeking diverse variants. Moreover, recognition of scarce mint marks can trigger behaviors among the non-collecting public, which sustains long-term availability for hobbyists by reducing circulation and enhancing future market rarity.

Mint Marks by Jurisdiction

United States

The Mint established its mint mark system in the 19th century to distinguish coins produced at branch facilities from those at the original , which opened in 1792 and initially struck coins without any identifying mark. The served as the primary facility, producing the majority of circulating coinage without a mint mark until the introduction of the "P" symbol on certain issues starting in 1942, with consistent use across most denominations (except cents) beginning in 1980. Branch mints adopted specific letters to denote their output: the , operational since 1854, uses "S"; the , established in 1906, uses "D"; the New Orleans Mint introduced the "O" mark in 1838 upon its opening; and the employed "CC" from 1870 to 1893 for gold and silver coins tied to the silver deposits. Significant historical changes shaped the system, including a suspension of mint marks on most circulating coins from 1965 to 1967 under the , aimed at curbing during a coin shortage by making coins less distinguishable for collectors. Marks resumed in 1968 but were placed on the obverse side for some denominations, and the Philadelphia "P" mark was largely absent from 1968 to 1979 except for limited exceptions like the 1979 . In modern times, the , originally a bullion depository since 1938, began using the "W" mark for select circulating issues, such as 10 million in 2019, marking the first appearance of "W" on general circulation coins; following this, the "W" mark appeared on 2020-W and 2021-W to commemorate the quarter's centennial, and continues on select proof issues as of 2025. Notable coin series highlight the role of mint marks in U.S. , such as the Mercury dimes produced from 1916 to 1945, where "D" and "S" marks identified branch mint output, including low-mintage keys like the 1916-D with just 264,000 pieces struck. The program (1999-2008) incorporated "P", "D", and "S" marks on its designs honoring each state, with over 34 billion total quarters produced across the facilities to facilitate widespread collection. These variations underscore how mint marks aid in tracing production origins and rarity within specific series.

Selected International Examples

In , the Royal Canadian Mint, established in in 1908, introduced the "C" mint mark on gold sovereigns produced from 1908 to 1919 to indicate Canadian origin, distinguishing them from those struck at the London branch of the Royal Mint. This mark appears on the reverse above the date, reflecting the mint's role in supporting local gold refining and coinage during the early . Since 1976, the branch has used a "W" mint mark on select issues, such as certain commemorative coins. Coin designs from the Royal Canadian Mint often incorporate bilingual elements in English and French, honoring Canada's two official languages, as seen in commemorative issues that feature dual inscriptions to promote cultural inclusivity. The United Kingdom's has traditionally omitted routine mint marks from circulating coins due to centralized production, first at the and later at since 1968. Instead, historical privy marks—small symbols denoting special strikings—appear on select , such as proof issues from the early , including variations on the 1817 design that revived the modern sovereign format. These privy marks, often subtle engravings like plumes or anchors, helped identify limited-edition or commemorative pieces without altering standard circulation designs. In the , mint marks on introduced in 1999 vary by issuing country to identify production facilities while adhering to unified European standards, with the outer ring featuring 12 stars symbolizing unity. For instance, uses the letter "R" for coins struck at the Mint, positioned near the national design on denominations from 1 cent to €2. employs a lion's head symbol as its mint mark, reflecting national and appearing on the obverse of coins produced at the Finnish Mint in . Smaller non- states issuing , such as , , and , often rely on external mints but incorporate country-specific motifs; their designs may reference the European map on the common side for €1 and €2 coins, emphasizing continental integration without unique mint symbols in all cases. Australia's minting system features distinct marks across its branch facilities, with the adopting the "P" symbol since its opening in for gold sovereigns sourced from local mines. This mark continued into the decimal era launched in , appearing on select silver and coins to denote Perth production, such as on certain 50-cent pieces and commemoratives. Early decimal issues from other mints, like , typically lacked marks due to the closure of the facility in 1926, but Perth's "P" provided clear for regional output in the post-1966 series.
