noted that some of the Janapadas like shakiya during Buddha's time were minting coins both made of silver and copper with their own marks on them.The study of the relative chronology of these coins has successfully established that the first punch-marked coins initially only had one or two punches, with the number of punches increasing over time. The first PMC coins in India may have been minted around the 6th century BCE by the Mahajanapadas of the Indo-Gangetic Plain, The coins of this period were punch-marked coins called Puranas, old 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. They are mentioned in the Manu, Panini, and Buddhist Jataka stories and lasted three centuries longer in the south than the north (600 BCE – 300 CE). Uninscribed Cast Copper Coins A small square bronze coin recovered from Pandu Rajar Dhibi has a primitive human figure on obverse and striations on reverse and may recall striated coins of Lydia and Ionia in 700 BC may well be dated before the punch marked coins of ancient India. Cast copper coins along with punch marked coins are the earliest examples of coinage in India, archaeologist G. R. Sharma based on his analysis from Kausambi dates them to pre Punched Marked Coins (PMC) era between 855 and 815 BC on the basis of obtaining them from pre NBPW period, while some date it to 500 BC and some date them to pre NBPW end of 7th century BC. Archaeological excavations have revealed these coins both from PMC and pre PMC era. The dating of these coins remain a controversy. Die struck coins According to some scholars Punch marked coins were replaced at the fall of the Maurya Empire by cast, die-struck coins. The coin devices are Indian, but it is thought that this coin technology was introduced from the West, either from the Achaemenid Empire or from the neighboring Greco-Bactrian Kingdom. Saurashtra die struck coins (5th century – 4th century BC) Saurashtra Janapada coins are probably the earliest die-struck figurative coins from ancient India from 450 to
