I have no idea what this coin is. It could be worthless for all I know Im just curios about it Also wondering country of origin and year it was made.
Sorry not to be more help, but the coin is Chinese (Taiwan) and is year 62 (from what i don't know) and has a value of 5 of some unit. My wife is Japanese and she could tell this much.
