Hearclea did good work at that period and seems to have applied silver more efficiently judging from the number of silvered coins we see. ro's is as nice as I have seen. They come is several minor variations/series. This Licinius I has a Λ to the right of the gate and mintmark SMHA. My Constantine has mintmark MTHB making it the common type but the B could be misread as a Δ which is not listed. Sometimes with these you need to see what was intended rather than what you want to see. Constantine II here shows MHTE. E shop seems to have made rare coins for some of the others but was primarily used for young Constantine. Even in lesser condition, there is a lot of silver remaining. How did Heraclea do this? Missing from my set is the MHTΓ struck for Crispus. I don't even have a similar one since I sent the coin below into exile (who got it???). This gate is Crispus SMHΓ but with two turrets and a star dating later after the removal of Licinius. I do not know if it ever had the heavy silver or did that practice go away with Licinius? There are many things to be studied by a serious student of Late Roman Bronzes. The coins are not expensive but the work required to be a specialist is considerable. Thanks to ro for showing that really nice specimen.
No campgate for me, but I have one of these: Licinius II, Caesar, AD 317-324 Roman Æ follis; 17.55 mm; 3.36 gm Antioch, AD 317-318 Obv: D N VAL LICIN LICINIVS NOB C, laureate bust, left, holding mappa in the r. hand and globe and scepter in l. Rev: IOVI CONSERVATORI CAESS, Jupiter standing left, holding Victory on globe; resting on scepter; at left, captive. SMANT in exergue, H in field, r. Refs: RIC 29; RCV 15415.
Here is the missing Crispus. MHT<gamma> Silvered. Old scan, sorry. Here's another Crispus but with the .MHT<gamma>. mark, fully silvered. Another old scan.
