Awhile back i found this coin on the beach in Oregon,along with some others.I have been told that this coin is possibly from the Qing Dynasty period 1664-1912. I have been having a hard time finding somebody qualified to authenticate this coin.I was told that the symbols on the obverse are in Chinese and Manchu.Apparently this did happen but it is supposed to be of the rarest.If anybody has any leads to anyone in the Pacific Northwest corner of Oregon i would greatly appreciate it.
