I have a small hoard of China cash coins for swap. These are outside my normal area of interest so I can't identify the particular varieties. I think these are:

But again, I can't be sure! For that reason, I'd like to swap these coins as a group. Take a look at the photo and PM if you're interested:



PS: there are about 70 coins here. Some might be tourist copies, but most look authentic to me.

PS: I also have several copper and bronze cash coins in my swap list. Those were a bit easier to identify!

Thanks you to member @gros for helping me identify some of these pieces.

As expected, there are many tourist copies in this group, but looks like some are authentic:





I hope to narrow down the exact varieties on these pieces and complete a swap this week. Thanks again to @gros for all the help.
