Nummus - Procopius REPARATIO FEL TEMP, Cyzicus

Procopius seized power in Constantinople on September 28, 365, exploiting the absence of both emperors — Valentinian I was on the Rhine, Valens was in Cappadocia — and his own tenuous blood connection to Julian's family as his sole claim to legitimacy. The Cyzicus mint, geographically within his controlled territory, struck coins for him throughout the usurpation. His reign lasted less than eight months before Valens crushed him at Thyatira in May 366; Procopius was beheaded shortly after.

The REPARATIO FEL TEMP type was already an established reverse for the legitimate Valentinianic dynasty, making Procopius's adoption of it a deliberate act of political mimicry rather than independent iconographic choice.
