Watch List notes:

IONIA, Uncertain mint. 5th century BC. AR Tetartemorion (6mm, 0.19 g). Head of eagle left / Four-spoked wheel within circular incuse. Apparently unpublished, but see Gorny & Mosch 204, lot 1516; cf. Münzen & Medaillen GmbH 30, lot 491. VF, toned, light porosity. Very rare.

Although previously given to Magnesia in previous auction appearances, the known types (head of eagle / wheel) are not specific enough to assert such an attribution.
