Pontos, uncertain mint, AE, ca. 120-100 BC. 1.51 g.

Horse's head right above eight-rayed star. 
Eight-rayed star, palm branch at upper left.

BMC Black Sea 984; Stancomb 653.

With permission of Rauch GmbH auction 92, lot 1084, April 2013.

Note - the front of the horse's head, if that is indeed what it is, is quite peculiar, with what appears to be a <- shape at the front. My first thought was that the object was an eagle standing left, with the <- shape being its tail.
