Nummus - Constantinus I VRBS ROMA, Arelate

VRBS ROMA types were struck across the western mints beginning around 330 AD as part of a commemorative program tied to the re-founding of Constantinople — an odd pairing, since the type honors old Rome while the political center was shifting decisively east. The Arelate mint (modern Arles) had been elevated to major status by Constantine himself after he wrested control of the west from Maxentius in 312, deliberately building it up as an imperial production center close to his favored Rhineland campaigns.

RIC VII 400 places this piece among the later Arelate emissions, struck just two years before Constantine's death in 337.
