I've tried everything i could think of on Google but nothing. Anyone know about this one. Its an interesting coin.
Unfortunately my google skills aren't producing any results. edit: google skills to the rescue! this was the search that got the result: "1905-2005 Chinese anniversary" https://en.numista.com/catalogue/pieces9387.html 1 Yuan - China - Liao Chenyun (100th Anniversary of Chen Yun)
From what I can tell, that is a 1 Yuan 100th anniversary of Chen Yun, an important political figure in the Communist party in the People's Republic of China. So, to conclude, it is a Chinese 1 Yuan coin (I don't think its silver, but wait for one of the other foreign coin experts to verify that).
