I've got this Gallienus AE and the surface makes me wonder if it is a cast fake.
GALLIENVS AVG, Radiate bust facing to the right.
ABVNDANTIA AVG, Abundantia, standing to the right, holding a Cornucopia with both hands, emptying it to the right.
B in the left field.
Weight: 1.70 g, Diameter: 17 x 17 x 1 mm, Mint: Rome, Reference: RIC 157
I may well be jumping to unreasonable conclusions, since I know that the AE's of Gallienus were mostly low in quality, compared to coins of the rebel, Postumus.
