03/24/17 at 17:10The river god, depicted on the reverse of this coin, appears very similar to a Phokaia Hekte emission obverse - Phokaia Bodenstedt 16. In the Gemini Auc. X (1/2013) lot 110, the cataloguer describing an example of the Phokaia B 16 Hekte suggested:"The man-headed bull is likely to be the river god Acheloos. A kindred representation can be found on coins of Cyzicus (Gulbenkian Coll. 607)".
