Dunno, Joe. It's ambiguous. I actually deleted my earlier reply - you may have been the only one who read it before I did so. I speculated that the obverse might be Apollo since the bust is very similar to some Seleucid (and other areas') renditions of Apollo, with the tubes of hair hanging down behind the neck. But then I got to wondering if the figure might be helmeted, which would negate that idea. Is the bust helmeted or not? Is it male or female? I can't tell. So, for me at least, both the obverse and reverse are head-scratchers.
