Æ21 - Severus Alexander ΝΙΚΑΙΕΩΝ

Nicaea's civic bronze coinage under Severus Alexander was produced during a period when the city was actively competing with Nicomedia for provincial prestige — a rivalry that drove both cities to issue coins in volume as public demonstrations of loyalty and civic standing. Nicaea had been the site of Diocletian's later administrative reforms, but under Alexander it remained a secondary seat, channeling that ambition into its mint output.

The VI#3147 reference places this within Voegtlin's corpus of Bithynian civic issues, a classification system that remains the standard for this regional series despite its age.
