Aureus - Constantius I HERCVLI VICTORI NK, Nicomedia

Constantius I ruled as Augustus for barely fourteen months before dying at Eboracum (York) in July 306, making any gold struck in his name as sole western emperor exceptionally short-lived in production terms. This Nicomedia issue belongs to that compressed window following his elevation after Diocletian's abdication in May 305 — a political restructuring so carefully choreographed that both retiring emperors abdicated on the same day in different cities.

Nicomedia was Diocletian's preferred eastern capital and retained that mint's prestige infrastructure after his retirement to Spalatum.
