Diademed head right, wearing aegis / Eagle standing left on thunderbolt; to left, P above monogram. Svoronos 256 var. (small Δ behind ear); SNG Copenhagen –; Noeske 29 var. (same).

This piece is of a somewhat irregular style, and lack the small Δ behind Ptolemy's ear, so it is possibly a contemporary imitation.
