Obv: ANTWNIOC GOPDIANOC AVG / AVT KM, confronted busts of Gordian and Serapis
Rev: DIONVCO-POLEITWN, Dionysos naked, standing facing, holding cantharos 
 above head and bunch of grapes (?) (thyrsos ?), panther at foot right. 
 Value "E" in left field. 

Moushmov 120 var.

(Moushmov and Varbanov describes Dionysus as holding a thyrsos but their 
 examples are a mirror image of this coin - this seems to be a bunch of 
 grapes.)
