The first coins in India were minted around the 6th century BCE by the Mahajanapadas of the Indo - Gangetic Plain, and certainly before the invasion of Alexander the Great in the 4th century BCE. The coins of this period were punch - marked coins called Puranas, Karshapanas or Pana. Several of these coins had a single symbol, for example, Saurashtra had a humped bull, and Dakshin Panchala had a Swastika, others, like Magadha, had several symbols. These coins were made of silver of a standard weight but with an irregular shape. This was gained by cutting up silver bars and then making the correct weight by cutting the edges of the coin.
