Here's a piece that I was wondering about. It's silver, roughly the size of a us quarter and possibly upside down. Thanks!
I would say it's Morocco. But I think, it is not a coin but jetton or medal. I can't find such coin in my catalog.
It's a commonly seen novelty piece modeled after the design of Ottoman Algeria coins. They are usually holed and presumed to have been used for ornamentation such as belly dancer costumes.
