During the 1700s when people were deciding this stuff they often looked at the headgear. Laurel wreath=Apollo, simple corn wreath=Kore. Here is one called Kore: Kyzikos AE20 5.33g 1st-2nd century AD Head of Kore right, grain ear in hair; within a wreath of grain K-Y/ZI, caduceus, in the center of which is a gorgoneion, the handle is made of a club, crescent above, tunny below, monogram right; all within a laurel wreath. RPC I 2240; Von Fritze 45, pl. iii, 5; SNG Copenhagen 86; BMC Mysia pg. 40, 170; SNG von Aulock 1245 This one is interesting because the "caduceus" on the back is some kind of crazy crescent (moon?) and has a gorgon's head decoration.
