ca 550-530 BC. AR Hemiobol (0.46g). Head of bear left, holding tunny fish in mouth / Quadripartite incuse square ("mill-sail" pattern). Extremely rare. EF.
I believe an example of this coin is published - Rosen 374 (attributed to Asia Minor Uncertain Mint). The reference does not recognize the tunny fish element, which is much clearer on the example here.
