I wish I could help you with this - I have a box with a few like this - Middle Eastern or Indian coppers. Sometimes I poke around with Google image search and get lucky. Mostly I get stumped. You might try the World Coin forum for help. I am not entirely sure your coin is ancient - I recently got an Indian copper dump I figured was at least 17th century but it turned out to be from 1936 A.D.! Good luck and welcome to Coin Talk.
