Nummus - Constantinus I CONSTANTINOPOLI, Cyzicus

The CONSTANTINOPOLI commemorative series was struck beginning in 330 AD to mark the formal dedication of Constantinople as the new imperial capital — a political act Constantine had been building toward for years. Cyzicus, one of the busiest mints in the eastern empire, was among several facilities ordered to produce the type simultaneously. The RIC VII 93 attribution places this piece within a specific officina sequence at Cyzicus, where mint-mark variations allow relatively precise workshop identification within the broader commemorative run.
