Coin shortages in 1985 saw the use of the Birmingham Mint, the British Royal Mint for the manufacture of 1 Rupee coins and a South Korean Mint for 50 Paise coins. Then in 1988 the Royal Canadian Mint made around three-quarters of a billion pieces in total of the new steel coins introduced to India that year. The more recent coin supply problems in India have again given the RBI the need to look to foreign mints for the supply of some coins.
