Helmeted head of Athena right, with profile eye and pi-style palmette / Owl standing right, head facing; olive sprig and crescent behind. CNG E-427, lot 194 (same dies), otherwise unpublished.

The thick and compact flan suggest an eastern origin for this imitation, possibly as far as Baktria or northern India.
