I was given this coin and do enjoy the horse & rider image on the reverse, however I have no idea who this coin represents, the individual who gave it to me guessed Crispus, but that was just a ballpark... Does anyone have a better opinion??
Try CRISPINA-Nikopolis. The legend on the Obverse spells KPICPEINA in Greek, it is a Provincial coin not Imperial. I have done a quick search and cant find it, definitely Crispina but the Reverse evades me.
