GREEK COINS
Kings of Thrace

Lysimachos, 305-281 BC. Stater (Gold, 18mm, 8.45 g 12), uncertain mint, perhaps in Thrace, c. 250. Diademed head of Alexander the Great to right, with horn of Ammon over his ear. Rev. ΒΑΣΙΛΕΩΣ ΛΥΣΙΜΑΧΟΥ Athena seated left on low-backed throne, holding, in her right hand, Nike crowning the king's name and, in her left, a spear, and with her left elbow resting on a shield ornamented with an aegis; to left, ΣΙ. Müller -. Thompson -, apparently unpublished. An attractive piece struck on a broad flan. Obverse struck slightly off center and with a bang on the reverse edge, otherwise, about extremely fine.

From a European collection.
Exactly where this coin was struck is uncertain, but stylistically it looks like early posthumous issues from Byzantion, Kalchedon and Lysimacheia, so it is presumably from somewhere in that general area.
