China Token Or Coin?

There are several dies involved in the type. I would not believe the ebay prices because you can ask for any price. So far no one has traced or attributed the item to any reference book.

This piece could be duplicated rather easily even with dental plastic to create a die pair capable of striking a brass copy. There are other methods for larger batches. Steel dies would cost about $1500 but they might make 100,000 copies in soft brass.

I suspect a copy of a rare original is far more likely.
