According to the Coinage Act, 1906, the Government of India has the sole right to mint coins. GOI supplies the coins to Reserve Bank of India which then circulates the coins.
As per the Coinage Act, 1906, coins can be issued up to the denomination of Rs.1000. Coins in India are presently being issued in denominations of 50 paise, one rupee, two rupees, five rupees and ten rupees. Coins up to 50 paise are called ‘small coins’ and coins of Rupee one and above are called ‘Rupee Coins’. Coins in the denomination of 1 paise, 2 paise, 3 paise, 5 paise, 10 paise, 20 paise and 25 paise have been withdrawn from circulation with effect from June 30, 2011 and are, therefore, no more legal tender.
Coins are received from the Mints and issued into circulation through its Regional Issue offices/sub-offices of the Reserve Bank and a wide network of currency chests and coin depots maintained by banks and Government treasuries spread across the country. These offices issue coins to the public directly through their counters and also send coin remittances to the currency chests and small coin depots.
