Got these for around $12 on e-bay. I know nothing spectacular, but good for me to try and identify... Now, I started out with this one as a Constantine Campgate (3.13 g 18 mm) and the closest I could come was Constantine I, 317 AD, RIC VII 16B, Herculea mint
I think you did quite well. I've done similar, buying a few from LCS (who doesn't generally have Ancients) to try to attribute them, and haven't made any progress, lol. I haven't decided if I'm stupid, or just "educated beyond my intelligence".
Thanks, it's just that there are some minor differences, such as the gate having 7 layers instead of 6...
