Nummus - Constantinus I MARTI PATRI CONSERVATORI, Treveri

The MARTI PATRI CONSERVATORI issue from Trier belongs to a politically charged moment: Constantine was not yet emperor by any orthodox measure, having been proclaimed by his troops at York in 306 following Constantius I's death — an act the senior Augustus Galerius refused to fully recognize. The Mars reverse was a deliberate alignment with Maximian, whose patronal deity it was, cementing the short-lived alliance through which Constantine received the rank of Caesar rather than the Augustus his soldiers had demanded.

RIC VI 772a is a scarce variety within the broader Trier output of this period. The mint was operating under considerable political pressure to assert dynastic legitimacy through coin production.
