Obverse: Veiled, female bust right (possibly Berenice II). Reverse: Marathos standing left, resting elbow on column, holding aphlaston.
Very nice coin, looking better in the hand than in the photo, in VF+/EF- condition, conserving complete details on both sides and a precious dark green patina.
HGC 10, 193. Marathos mint, middle 2nd Century BC. 9,35 g - 22 mm
