Uncertain (BC 480-420) Hemidrachm

5th century BC. AR Diobol(?) (12mm, 1.76g, 12h). Lion at bay right / Facing gorgoneion within incuse square. Apparently unpublished. VF, surfaces a little rough.

The style of the gorgoneion is similar to another series of fractions with a different obverse type (featuring the elements of a chimera, cf. CNG 85, lot 477 and Lanz 150, lot 162). Unfortunately, that series also cannot currently be assigned to a mint.
