Nummus - Constantinus I VRBS ROMA, Siscia

The VRBS ROMA issues were struck across multiple mints simultaneously beginning in 330 AD, launched to commemorate the formal dedication of Constantinople as the new imperial capital — a deliberate propagandistic pairing with the CONSTANTINOPOLIS type issued at the same time. Rome itself had not been the operational seat of imperial government for decades by this point, making the issue something of a nostalgic fiction. The Siscia mint, located in modern-day Sisak, Croatia, was one of the western empire's most productive bronze facilities during the Constantinian period.
