Hi,
Thank's for the replies.
I'm not an expert on this matter, but i never like chinese coins because of the FAKE coins they make.
Is there any expert on this...?

I have a section 'Fakes' in my coin collection.
There are indeed people who collect these 'coins'

Forgeries are sometimes made in silver.
First try a magnet, ping-test
Buy some neodymium magnets to make a coin slide (very usefull):

Silverplated copper gives the same effect.
This is how it works:

All are replicas which selling for around 3 RMB in China so don't even think there's any silver.

Quote: "LCW1991" All are replicas which selling for around 3 RMB in China so don't even think there's any silver.I've seen markets selling hundreds of these fakes in trays in East Asia, so if your friend bought them in a similar setting there's a 99.9999 chance they're fake.
That .0001% chance is then squashed by the clumsy details on the coins, and the fact that the second to last coin (claiming to be from Tibet, or Xizang in Chinese) doesn't actually exist.

A actual 100% Silver coin of this size, 39mm, would weigh 37.5 grams if about 3mm thick. 2 mm would make it 25 grams.
Therefore a 39mm, 3mm coin with a weight of only 26-27 grams is either silver plated on some alloy (or copper) or a low silver content type of alloy.
Some of the information stated on numista is therefore incomplete when it states "Silver" for these coins.
It also makes me believe that most of these coins are (all) dubious because the actual allloy is unknown.

It could be true if the average coin thickness is about 2.6mm.
These guys and or girls are also mentioning these weight values:

The amount of fakes is huge, copper silver plated ones are difficult to distinguish as the weight can be similar.

Sure.
Compare the supposed 26-27 g 39mm 3mm silver coin to this:
https://en.numista.com/catalogue/pieces3851.html
A 35.4 g silver (0.877) 39mm 2mm coin (which according to theory has a maximum of about 23-25 g)
