coin determination

Hello.
Do you have any idea about this coin (diameter 40.80 mm)?
It could be a fake one as a huge part of chinese coins are fake.
Regards.

Hello,

This is probably some kind of token or charm; by my guess it's probably older than modern replicas of cash coins though!

It's got the name of Qing emperor Yongzheng on it; given the phrase on the reverse (Peace under Heaven) it could be a Palace Cash amulet like this one:

(That particular one linked is probably a fake but yours does look nice and old, so....)
