5th century BC. AR Hemiobol (7mm, 0.36g). Horse’s head right / Rough incuse square. Good VF.

While such coins are generally assigned to an uncertain Thraco-Macedonian mint, the style of the current coin is more refined than any of the horse types in Tzamalis. “Horse/incuse” types were almost certainly minted at multiple locations, and a mint in (western?) Asia Minor would seem logical based on provenances.
