A cheap pick up for a first Centaur reverse for me. Post your Centaurs Gallienus AE Antoninianus. Sole reign 260-268AD. GALLIENVS AVG, radiate head right / APOLLINI CONS AVG, Centaur walking left, holding globe and trophy. Mintmark H in exergue. RIC 164a, Cohen 74, RSC 74. Sear 10177.
Mine is ancient Greek I think that is Zeus on the front. Thessaly, Magnesia 196-146 BC, Bronze AE19 Late edit: I'm sorry, I see you want only Gallienus
No, yours is spot on, in the first line on my OP it says show your Centaurs. Yours is a nice example.
