The currency of the country of India is the Rupee which whs a history going back several hundred years. Its coins were struck in silver for a quite a long time and even in the 1800s when other countries were backed in gold. At one point during that time the supply of silver increased leading to a price drop which caused a problems for the Rupee in the 1800s. Indian went on to a decimal system for their currency in 1957.
