Archaic Silver Punch Marked, Bihar series, generally attributed to Magadha Janapada of pre-imperial period, Silver Vimshatika, 5.35g, Obv: Four punches - 1. Sun, 2. Six-armed symbol (in centre), 3. Crescent, 4. Sacrificial spoon; other smaller marks around, Rev: Minor 'banker's marks' (Rajgor Series 10). Extremely fine, extremely rare.
This is probably the earliest coinage struck in the Magadha region, with a prominent 6-armed symbol in the centre. Struck to the Vimshatika standard, these coins ostensibly were produced at par with the early coinage of the neighbouring kingdom of Kashi. The economies of Magadha and Kashi were linked by trade through the Ganga river.
