Yuan Shikai dollar and jiao : fake or real ? [solved]

Hello,
About 12 years ago I got the followings coins from the same dealer at a french flea market.
First I thought there were genuine, but few years later I heard that most of those coins are fake.

Since then, I considered them as doubtful... until I decided last week to have a second look at them and doing some tests.

The dollar :


The jiao :


They both seem to be in silver (ping test and ice test are ok !).
The first one weights 26,47g for 39mm and the second one 2,66g for 18,5mm : that seems good too.
The wear looks real to me.
The coin edges are both reeded and they both are medal alignment...

However I still have a big doubt about the fat man dollar because of the bubble things at the top... The coin doesn't seem cast, however it seems that something happened there : the edge is a bit thin at this particular area like it was "punched" / heated. Perhaps it was used as a pendant ?

Another point, the dollar was probably double strucking / struck on another coin :



​I guess if one is a fake the other one should be fake too.

Frankly, I've never seen à silver coin with such a surface aspect (holes, grain) like on the reverse of your dollar

Separately the jiao is more likely to be real than the dollar, but if you got them from the same vendor I think chances are they're both either real or fake. Smaller silver and even copper coins have been known to be forger targets.

On the dollar I'm 75% convinced it's fake, because of the unnatural looking wear around areas like the bottom of the wreath and his face, as well as the lumps around some of the characters above his head. I could be wrong, though.

The grain aspect is due to multiple micro shocks on it, but it looks quite weird : it could have been done intentionally to look older.



About the wear I assume the coin has been cleaned at some point. It looks more "normal" with the naked eye but I can be wrong :


The lumps around the characters seem to correspond with ideograms (民 and 華 ?) : it's the reason why I assumed there was a previous struck and it could be genuine after all.

they look like cast fakes/forgeries/replicas

​I don't think so, especially with 民; there are lumps to the left and right of the character that seem particularly suspicious.

Thanks for your answers !
I will consider them as fakes in this case
