Anyway, I have been collecting ancient and medieval coins for years now, and I have never seen anything quite like this. There doesn't appear to be any inscription, and it only features random lines and dots. The closest things I've seen are irregular Anglo-Saxon sceattas and stycas, and possibly some sort of imitation of Judean coins of Alexander Jannaeus. Although neither of these seem quite right. The coin itself is about 13x11 mm in diameter and about 1 mm thick maximum. Any identification help is greatly appreciated, and I'm excited to become a user of this website!
