Chinese cash coins - ID to confirm

Hi everyone,

I have recently acquired a mixed lot of 20 cash coins. I am using Hartill to try to identify them but I'm very new to this. Here are the first four which I think are all authentic. They are also very common and ─I would think─ unlikely to be counterfeited. Open in new tab or window for best resolution (first pic done with the Leuchttürm microscope; other two with an iPad Air):

Feedback appreciated.

~~~~~~~~~ EDITS ~~~~~~~~~
Is this one in the catalogue my #1? I'm not sure because the character on the right side is not exactly the same. Mine looks more like the bottom left coin on this picture.

I think this one in the catalogue is my #2 and this other one my #3. I didn't find my #4.

They look genuine
4) Da Quan Wu Shi DH# 9.1-11

Thanks much, FrenchLover,

I see that Fred37 on the French forum came to the same identification. Here is a better photo where you'll see better the shape of the top character ─ actually, of all characters:



Is this just a variant of the same that you linked, or listed as a different coin?

They both are the same. This coin has a value of fifty cash and one cash is equiv. to 5 Zhu (1 Wu Zhu).

By the way the rust for this coin doesn't look impressive, to be honest, but still no doubt on its authenticity.

Thanks LCW,

I see that you also confirmed my IDs for my #1─3. I believe my #2 is the large characters variety like the one illustrated on the coin page.

I was also a little concerned about the patina at first, but I do believe it's authentic. The photo accentuates the green colour.

I will have more of these to show in coming weeks. The opinion of experts like you and FrenchLover will be welcome.
