Is my Chinese cash coin fake? [решено]

My dad got this coin from his aunt after she had been to China when he was a kid. I have heard that that many fakes were made to sell to tourists. Is this coin real or fake?

Gros is correct, this is genuine. While having good historical context and interesting to have in a collection, these are too common and low value to be faked.  A cash of emperor Qianlong aka Ch'ien Lung aka Kao Tsung, 1736-1795. mint Boo Yuwan (Board of Works, Beijing).
