Sorry about the photos, but this seems to be the best I can do. It is 17 mm and weighs 4.31 grams. Obverse: Round thing (shield?) in wreath (?). Dotted border, what looks like an E Reverse: Bearded guy (?) in military attire and "eastern" crown (?) striding left holding scepter(?) and wreath. RE - (Δ?)-Θ (theta). I can't make out any other letters. Unidentified object right - bungled caduceus or lobster? It vaguely looks like a Koinon of Macedon issue, but only vaguely. I'm stumped. Any help greatly appreciated.
