I picked up this Crispus from Lyons a few weeks ago from @Victor_Clark. This now puts me at 6/13 mints for PROVIDENTIAE CAESS campgates issued for Crispus. I believe only Arles and Rome minted VIRTVS CAESS types for Crispus, of which I've got Arles. So I guess I'm at 7/15 total. This one is by far the nicest. Crispus A.D. 324- 5 18mm 2.9gm FL IVL CRISPVS NOB CAES; Laureate, draped and cuirassed bust right. PROVIDEN-TIAE CAESS; camp gate with two turrets and star between them. in ex. PLG RIC VII Lyons 227 This next one came with the Crispus and it is my first coin of Licinius. Also a campgate and I think I got the attribution right with RIC VII Heraclea 17A, it might be a delta though? Did I mention this coin was free? I was very shocked opening that package to see two coins. What a great guy that Victor is! Licinius AD 317 19mm 2.6g IMP LICI-NIVS AVG, Laureate draped bust left, with globe, sceptre and mappa / PROVIDENTIAE AVGG, campgate, three turrets, 6 to 8 layers, no doors. Mintmark MHTA The last two I got because I felt I was lacking coins from Constantine. First up another campgate, of course, with a series mark I haven't seen before. I probably just haven't paid enough attention. Constantine I 19mm, 3.16g Diademed head of Constantine right "CONSTANTINVS AVG" Campgate "PROVIDENTIAE AVGG" "ASIS (doubled "U")" RIC VII 214 Siscia Struck 328-9 This last one is pretty neat. It refers to Constantines victories over the Sarmatians in 322. Constantine 307-337 AE3, 2.50g Obv: Diademed head of Constantine right "CONSTANTINVS AVG" Rev: Victory advancing right holding a trophy, captive at her feet "SARMATIA DEVICTA". RIC VII 49 Sirmium. Struck 324-5 Please share anything you think relevant.
