I'm not sure what to think about this coin. It looks like it was struck in a collar, which would mean that it is a fake or a souvenir. In addition, the legends seem to be in a mix of the Roman, Greek, and other alphabets.
I'm not saying it's a fake, just suggesting that it is a possibility.
At the bottom of the reverse (1st picture) I think we have the name ΠΡΟΤΟΥ = "of Protos".
