I think this is a maiorina of Margentius.
DN MAGMEN-TIVS PF AVG
VICTOR[IAE DD NN AV]G ET CAE
With the winged victories in the reverse holding a VOT V MULT X inscription. And a I below.

The mintmak looks like LPLC. Perhaps RPLG of Lyon?
But I see no remains of an A behind the head of the emperor. The ones I founs have that A.
What did the A mean? And why VOT V if he only reigned 3 years?
