The India Government Mint (ISO: Bhārata Sarakāra Ṭakasāla) operated four mints in the country for the production of coins:

The functions of the mint were replaced by the Security Printing and Minting Corporation of India in 2006.

Under The Coinage Act, 1906, the Government of India is charged with the production and supply of coins to the Reserve Bank of India (RBI). The RBI places an annual indent for this purpose and the Government of India draws up the production programme for the India Government Mints on the basis of the indent.

Besides minting coins, the mints at Mumbai, Kolkata and Hyderabad also make coin blanks. Hyderabad, Mumbai and Kolkata mints have gold assaying facilities and the Mumbai mint produces standardized weights and measures. Mumbai Mint has a state-of-the-art gold refining facility up to 999.9. Hyderabad Mint has electrolytic silver refining facility up to 999.9.

Commemorative coins are made at Mumbai and Kolkata. Kolkata and Hyderabad have facilities for making medallions, too. The Noida mint was the first in the country to mint coins of stainless steel.

Each currency coin minted in India (and anywhere in the world) has a special mint mark on it to identify the mint.

On renaming of the city of Bombay to Mumbai the coins minted carried the following mint marks: (1) The letter "M" (2) Double Diamond Mark - Proof Coins
