Nummus - Constantinus I GENIO POP ROM; Ostia

This issue belongs to a pivotal window: Constantine had just defeated Maxentius at the Milvian Bridge in October 312, and the Ostia mint — reopened by Maxentius himself around 308 to service Rome — was briefly operating under new authority. The GENIO POP ROM type was a Maxentian staple, and Constantine's continuation of it at Ostia in the months immediately following the conquest reflects deliberate ideological pragmatism rather than oversight. He was consolidating Roman loyalty, not yet ready to abandon familiar religious iconography.

The Ostia mint closed permanently by 313, making its Constantinian output genuinely short-lived. RIC VI 74 is among the final issues struck there before the facility was shuttered in favor of Rome.
