Gallienus, sole reign 260-268 IMP GALLIENVS AVG, Radiate head right ABVNANTIA AVG, Abundantia standing, emptying cornucopia RIC 157 Somewhat worn, but solid details with much better artwork on the reverse than is typical for coins of this period. Very nice political message! Glossy dark patina in hand. As mentioned before in my other ancients posts Much of this information was provided to me by a couple CCF members sharing their knowledge, I should credit them here. Thank you Finn235 and Paul Bulgerin CCF members. Who also supplied information and raw images which I have re-worked. I wouldn't know anything about them if it were not for their generosity and time taken to help make these more interesting. Late Edit, I replaced the picture. Thanks John Anthony
It has an unusually good reverse strike for an ant of Gallienus. Definitely a keeper! (But the picture you posted is Gratian, an emperor who came much later.)
