The coin looks easy to identify, with Zeus seated on reverse and holding Nike. The Greek lettering on reverse is not difficult to read MERROPOY maybe. Charming face on obverse, but not sure who that is. It's been offered to me with few valuable items which could be totally new in my collection. Please try to identify if you can.
