Authenticity of two, 10 Cash - Chongning Zhongbao cast coins [solved]

Hello new to the hobby and curious about two cast coins I have. They both seem to be the of the same type but have different characteristics.
I believe they are 10 Cash - Chongning Zhongbao.

I've heard its common to see fakes, my question is whether the one on the left with less precise making (uneven thickness on rim, wider characters, worse cast) is more likely to be real or is the one on the right with fairly precise making? Or is this a case of difference in casting and wear over time?


(Both are about 34-35 mm across, right most has slightly larger hole at 10 mm)

Are there any mint marks on the other sides? If not, those two are common variants for this type of Chongning era cash coin and they have many subtle differences between the H#16.407 and H#16.408 . I think they should be genuine.

Reverse is plain without mint marks. Looking up Hartill# 16.408 provided a number of cross reference images and after farther examination I realized that the varying thickness I saw on the rim was actually present on the opposite side of either coin, so I assume its likely related to the method of manufacturing.

Anyhow, I'll file them under likely genuine. Thanks for the reply!

The Chinese are very fond of these large coins, regardless of their authenticity

I wonder what kind of response you expect?
How do you expect to get an interesting opinion if there is no information? the weight, where you bought it, under what circumstances, we don't even have the photo of the reverse plain faces ...
If you want to know if "it looks like", well, you've the answer : Yes

The response I expected is near the response I got.
To a novice collector, such as myself, I might expect newer/thinner and more exact details to be evidence of a reproduction.
However I had read it was the opposite, thus asking about the difference between two of same cast coins I had seemed like a good way to get an idea of how I should approach the other coins I had yet to identify.

I gave all the information I figured would be of any use, I would not consider any of the missing information to be of any import in changing the responses. But sure, I could have added more.

* The back sides are plain, I did not think they would have any information of any value, they look exactly as the Numista picture

* I do not have a gram scale, my kitchen scale puts them at 12 grams, -+ .5 which is within range

* They were pulled out of a world coin bag from an numismatic side of an estate/jewelry dealer. Other coins pulled out of this bag have been genuine.

I have over 50 other cast coins I have put to the side to identify, I don't intend to bother others about them, but I'd like to at-least be able to gauge if they are likely to be genuine or reproduction/decoration.

(Coins in question, the two 10 Cash reverses are in the top left)

Hello

In the left of the picture they all look real There are 8 of them that look alike and are next to each other, they are Japanese Mon
on the right of the photo the 13 from the top also seem true to me but it would take more individual photos to be sure
For those who are below, there are many false ones, but perhaps not all of them.
Nice set anyway

​Good to know, will save me some time when I get around to identifying them all, I hadn't considered many of them would be Japanese.
I'll give them all a good once over before making a definitive decision.
Thanks for the thoughts.
