Cash coin [opgelost]

I have looked through the China Korea Vietnam and Japan listings but haven't found this coin. Anybody know what it is?

This is a modern replica/cash charm based on the Japanese Wadōkaichin, one of the scarce “12 antique coins” of medieval Japan. Here is both the Numista page of the real copy, and a Zeno link for another example of this modern charm:

Thanks for that.  I suspected it was not a real coin due to the lack of wear or corrosion.
