where did the first coins circulated in india
Coinage of India 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.[10]
Ancient Greek coinage The first known coins were issued in either Lydia or Ionia in Asia Minor at some time before 600 BC, either by the non-Greek Lydians for their own use or perhaps because Greek mercenaries wanted to be paid in precious metal at the conclusion of their time of service, and wanted to have their payments marked in a way that would authenticate them. These coins were made of electrum, an alloy of gold and silver that was highly prized and abundant in that area. By the middle of the 6th century BC, technology had advanced, making the production of pure gold and silver coins simpler. Accordingly, King Croesus introduced a double metal standard that allowed for coins of pure gold and pure silver to be struck and traded in the marketplace.
