The second picture looks better, thanks.
But it is still a very worn reverse.
Fortunately there aren't much Victorinus types to look on.
I think I got something, but a confirmation from an expert would be good.
I think the reverse may be VICTORIA AVG, there are a few on RIC, but only one with the obverse lettering that matches 100%: RIC V Victorinus 75, not yet on the Numista catalog.
