rome>roman empire>antoninianus - gallienus IOVI VLTORI; Jupiter 260-268DC [solved]

Good morning everyone, I can't find this coin in the catalog. Weight 2.11 grams, diameter 19 mm.

I sincerely thank anyone who can help me.  Giorgio

Hello — not sure whether it is in the catalogue, but to start it's a coin of Gallienus.

Obv.: GALLIENVS AVG

Rev.: MARS VLTOR (I believe, though only the VLTOR part can be read).

 Perhaps I letter at end, VLTORI which is on this

IOVI VLTORI, Jupiter walking left, head turned back, right hand raised, 

left holding thunderbolt; cloak flies out behind; S in left field. 

 though with obverse slightly different. 

The  S  on reverse is in the same place though. 

I think you're right. Nine times out of ten Mars is Ultor = the Avenger, but here we have Jupiter.

I'll check my catalogues and online resources later.
