Centenionalis - Constantius II VICTORIA CAESARIS, Siscia

Constantius II issued this type during one of the most precarious stretches of his reign — the usurpation of Magnentius in the West had just fractured the empire, and the Siscia mint was operating in contested territory. Siscia changed hands during the conflict, and coins struck there in 350–351 were produced under conditions of genuine political instability rather than routine administration.

RIC VIII 315 places this emission firmly in the early phase of the Magnentian crisis, before Constantius reasserted control at the Battle of Mursa in 351 — one of the bloodiest engagements of the fourth century.
