- Silver Punch-marked coins:
Silver Punch-marked coins- are the oldest coins of Bengal as well as of the Indian subcontinent. These coins were struck and circulated in the Mauryan period, during 4th century B.C to 2nd century A.D. Manufacturing process is the main reason for the nomenclature of these coins. Generally these coins were manufactured by cutting a certain amount of metal from the silver sheet or by melting the metal or by dropping it on a hard object then stamping the metal with a certain die. One to five symbols or sometimes more than five symbols were stamped on these ancient coins. There were no name of the issuer or his effigy or any indication but certain symbols were stamped on the coins obverses. The common symbols are sun, mountain or hill, hill top crescent, river, boat, tree, fish, bird, elephant, tiger, bull, rhinoceros, snake, arches etc. Two types of punch-marked coins have been found in Bangladesh, viz. Janapada or Local coins and Imperial series coins. Janapada or local coins have been discovered from a limited area and not found outside that particular area having up to 4 symbols on its obverses. Imperial series coins are found from various places all over the sub-continent having 5 symbols on its obverses. It is presumed that those coins were struck and circulated during the Mauryan period.
