Indian coins are a form of currency used in India. The two most common coins are Annas and RUPEES. Annas are five-letter coins that were first introduced in 1616 by the Mughal Empire. They were originally made of silver, but later changed to copper. RUPEES are six-letter coins that were first introduced in 1540 by Sher Shah Suri. They were originally made of gold, but later changed to silver. Both coins are still used today in India.
