Geta, AE27 of Nikopolis ad Istrum.

AVT K P CEPT GETAC AV, laureate, draped, cuirassed bust right.
V FL OYLPIAN NIKOPOLIT PROC I, Nike advancing left, 
holding uncertain, scroll-like object, and palm.

Varbanov 3298 (this coin; description corrected - not 
holding a trophy); AMNG 1669.

This is surely the best and clearest example of this
reverse, and yet it is still uncertain of what the 
object is, that Nike is holding.
