Irregular flat silver planchet, four punchmarks / Various bankers' punch symbols. 23mmx20mm, 3.18 grams. Rajgor Series 64, #962.
Most coins from Kasala show numerous punched banker's marks on the reverse. Applying these marks damaged and/or obliterated the obverse design, so it is hard to make out on many of these coins.
Kosala was an ancient Indian kingdom, corresponding roughly in area with the region of Oudh. Its capital was Ayodhya. It was a powerful state in the 6th century B.C. but was weakened by a series of wars with the neighboring kingdom of Magadha and finally (4th cent. B.C.) absorbed by it. Kosala was the setting of much Sanskrit epic literature including the Ramayana. Buddha and Mahavira, founder of Jainism, taught in the kingdom.
