I believe this coin is from Manchukuo. However, I'm not quite sure in regards to its origin. This coin is about the size of a Penny any information regarding it would be welcome.
East Hopei Province not Manchukuo https://www.ngccoin.com/price-guide...-5-fen-y-518-261937-cuid-1045871-duid-1287778
I think it is actually China Japanese Occupation East Hopei 5 Fen. Others with more knowledge will correct me. 1937? http://numismaclub.com/unt/90890-1937_china_japanese_occupation_east_hopei_coin_5_fen___y___617.html
