I found this coin in a lot.
Fortunately it was in a 2X2 with an inscription Wang-Mang 7-22 and I found a similar looking item: https://fr.numista.com/catalogue/pieces7318.html
But this one is much heavier: 6.5 grams and its diameter is 24mm.


So I have a couple of questions.
Is it the same coin or something else.
Common or rare?
And most important, as even very common old cash is being copied in China, does it look real or fake?
Thanks
