Watch List notes:

IONIA, Uncertain. 5th century BC. AR Tetartemorion (5mm, 0.20 g). Head of eagle left / Four-spoked wheel within circular incuse. Unpublished in the standard references, but for similar see Gorny & Mosch 204, lot 1516 and Münzen & Medaillen GmbH 30, lot 491. Good VF, toned. Rare.

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