Hello! My friend,as your coin looks I don't believe it is a genuine one but some copy/reproduction... Also,doublecheck if it surely silver minted or just silver-plated!
Andi Pasculescu hello dear it's silver
Naser Naser,if it is minted of good silver,the coin MAY BE genuine... The style is that of greek Byzantine coins. Real Byzantine silver coins are valuable and scarcer than their bronze or even gold coins! I am not expert in that coinage so I advise you to wait for a much accurate identification!
Andi Pasculescu thank you my dear
Naser -- Your coin looks like a replica. See genuine in my picture.
