As per Coinage Act, 1906, the Government of India has the sole right to mint coins and the responsibility for coinage vests with the Government.
The designing and minting of coins in various denominations is also the responsibility of the government.
Coins are minted at the India government mints at Mumbai, Alipore (Kolkata), Saifabad (Hyderabad), Cherlapally (Hyderabad) and Noida (UP).
The coins are issued for circulation only through the Reserve Bank in terms of the RBI Act.
