"Your coin seems to be from the same obv. die as von Aulock, Pisidien II, no. 568, pl. 13. ANTWNEINO before face, vA attributes to Elagabalus, though the same coin, in Athens, had earlier been published as Caracalla. Zeus seated right is a new type for Elagabalus at this mint, though vA has it both earlier, for Septimius and for Caracalla under Septimius, and later, for Sev. Alex. and Tranquillina."
