Again another Cash China coin. I guess. [opgelost]

I feel terrible not knowing even where to start to ID those coins.
Tried some "ID your chinese coins" websites with no sucess, also checked all pages of china empire on numista.
Might be super easy for chinese speakers, but I am not one of them.

So please, can anyone tell me anything about this one?

Diamater 24,5mm
One side is blank.




Sorry it is worn and the picture doesnt help.

Thank you for any comment,
