don't know, if you read the other comments, you will see i'm really uninformed about these particular coins, apparently they are Japanese, not chinese, and they are 'yen' sorry for the misinformation, i will add a bonus, coin for the winner. good luck and happy bidding!hohoho.
i collect coins from all around the world and i work at the airport and a Japanese guy gave some yen coins to me at the airport when the money exchange told him they only take paper money
