But thanks to Jochen this looks a better match:

Not Hermes with kerykeion but Dionysos with tyrsos holding wine grapes in extended r. hand!

obv. M OPELLIOC – ANTWN(EI)NOC, bust draped and cuirassed, bare-headed r.
rev. MARKIANO – P – OLEITWN
ref. Hristova/Jekov 6.25.8.1 (rare, R6); AMNG I/1, 797; Varbanov 1333
