Nummus - Constantinus I CONSTANTINOPOLIS, Lugdunum

The CONSTANTINOPOLIS type was struck across the empire from 330 to celebrate the formal dedication of Constantinople as the new imperial capital — a city Constantine had been building since 324 on the site of the Greek colony Byzantium. The Lugdunum mint, modern Lyon, was among the westernmost facilities producing this issue, making its coins geographically remote from the city they commemorated. This particular emission, dated 333–334, falls in the later phase of the type's production, by which point the reverse had shifted to the variant showing a Victory on a prow, distinguishing it from the inaugural 330 strikes.
