I have had these three coins for decades. I have researched trying to find a direction that will get me some information. I can't seem to get on the right track. And help would be appreciated. They appear to have some different symbols.
It's too late tonight for me to start on IDing them, and I am not great at it, but the following site is a great resource for identifying chinese cash coins. It's a fun pursuit, just too close to bedtime right now for me... http://www.calgarycoin.com/reference/china/chinaid.htm
The coins are from the Ching dynasty. "Qianlong Tongbao" from Emperor Qianlong. Time period is from 1735–1796. Here is the Wikipedia link with the mint mark info. Hope this helps. https://en.wikipedia.org/wiki/Qianlong_Tongbao
As the philosopher says, the journey always starts with the first step. By the way, you now have a collection. Cheers and happy hunting.
