Guinea (coin)
The guinea (/ˈɡɪniː/; commonly abbreviated gn., or gns. in plural) was a coin, minted in Great Britain between 1663 and 1814, that contained approximately one-quarter of an ounce of gold. The name came from the Guinea region in West Africa, from where much of the gold used to make the coins was sourced. It was the first English machine-struck gold coin, originally representing a value of 20 shillings in sterling specie, equal to one pound, but rises in the price of gold relative to silver caused the value of the guinea to increase, at times to as high as thirty shillings. From 1717 to 1816, its value was officially fixed at twenty-one shillings.
In the Great Recoinage of 1816, the guinea was demonetised and replaced by the gold sovereign. Following the Great Recoinage, the word "guinea" was retained as a colloquial or specialised term, even though the coins were no longer in use; the term guinea also survived as a unit of account in some fields. Notable usages included professional fees (medical, legal, etc.), which were often invoiced in guineas, and horse racing and greyhound racing, and the sale of rams. In each case a guinea meant an amount of one pound and one shilling (21 shillings).
The first guinea was produced on 6 February 1663; a proclamation of 27 March 1663 made the coins legal currency. One troy pound of 11⁄12 (0.9133)[citation needed] fine gold (22 carat or 0.9167 pure by weight) would make 44+1⁄2 guineas, each thus theoretically weighing 129.438 grains (8.385 grams crown gold, 7.688 grams fine gold, or 0.247191011 ozt (troy ounces) fine gold).
The coin was originally worth twenty shillings (one pound), but an increase in the price of gold during the reign of King Charles II led to the market trading it at a premium. The price of gold continued to increase, especially in times of trouble, and by the 1680s, the coin was worth 22 silver shillings. Indeed, in his diary entries for 13 June 1667, Samuel Pepys records that the price was 24 to 25 shillings.
The diameter of the coin was 1 in (25.4 mm) throughout Charles II's reign, and the average gold purity (from an assay done in 1773 of samples of the coins produced during the preceding year) was 0.9100. "Guinea" was not an official name for the coin, but much of the gold used to produce the early coins came from Guinea (largely modern Ghana) in West Africa.
The coin was produced every year between 1663 and 1684, with an elephant appearing on some coins each year from 1663 to 1665 and 1668, and the elephant with a howdah on other coins minted from 1674 or 1675 onwards. The elephant, with or without a howdah, was the emblem of the Royal African Company (RAC), which had been granted a monopoly on English trade with Africa in slaves, gold and other goods, from 1672 until 1698; gold imported from Africa by the RAC bore the elephant emblem beneath the monarch's head on the coin.
The obverse and reverse of this coin were designed by John Roettiers (1631–c. 1700). The obverse showed a fine right-facing bust of Charles II wearing a laurel wreath (amended several times during the reign), surrounded by the legend CAROLVS II DEI GRATIA ("Charles II by the grace of God"), while the reverse showed four crowned cruciform shields bearing the arms of England, Scotland, France, and Ireland, between which were four sceptres, and in the centre were four interlinked "C"s, surrounded by the inscription MAG BR FRA ET HIB REX ("Of Great Britain, France, and Ireland King"). The edge was milled to deter clipping or filing, and to distinguish it from the silver half-crown which had edge lettering. Until 1669 the milling was perpendicular to the edge, giving vertical grooves, while from 1670 the milling was diagonal to the edge.
John Roettiers continued to design the dies for this denomination during the reign of King James II. In this reign, the coins weighed 8.5 g (0.27 ozt) with a diameter of 25–26 mm (0.98–1.02 in), and were minted in all years between 1685 and 1688, with an average gold purity of 0.9094. Coins of each year were issued both with and without the elephant-and-castle mark. The king's head faces left in this reign, and is surrounded by the inscription IACOBVS II DEI GRATIA ("James II by the grace of God"), while the reverse is the same as in Charles II's reign except for omitting the interlinked "C"s in the centre of the coin. The edge of the coins are milled diagonally.
