Watch List notes:

MYSIA. Parion (?). 5th century BC. Hemiobol (?) (Silver, 5.5 mm, 0.27 g). Facing gorgoneion with protruding tongue. Rev. Stellate pattern within incuse square. Klein -. Rosen -. SNG BN -. Seemingly unpublished. Very fine.
From the collection of a scholar.

The attribution to Parion in Mysia is not firmly established, but seems logical based on the similarity of style to the well-known drachms from that city (cf. SNG BN 1351-2).
