I found this Chinese coin this past weekend. I can't find anything online about it. I looked around and could not find any that matched it. I don't believe it is that old. It is silver toned but not silver. It is corroding similar to zinc. Any help would be greatly appreciated. Thank you.
Your coin is similar to a cash coin minted during the 61 year reign of Qian Long (1735-1796).
Don't be surprised is the coin is a fake; many were.
