| Additional information |
Constantine's Danubian mint at Siscia — modern Sisak in Croatia — was one of the most productive bronze-striking facilities of the early fourth century, particularly during the period of nominal co-rule with Licinius that preceded their final rupture. The years 321–324 mark the last tense phase before Constantine moved against Licinius outright, defeating him at the Battle of Chrysopolis in September 324 and reducing the empire to sole rule for the first time since Diocletian's abdication.
The DN CONSTANTINI MAX AVG titulature — *Dominus Noster*, a form of address that subtly elevated the emperor toward the divine — became more consistently applied to bronze coinage from the 320s onward, a deliberate tightening of imperial nomenclature.
