Æ3 - Procopius REPARATIO FEL TEMP, Constantinopolis

Procopius declared himself emperor in Constantinople in September 365, exploiting the absence of Valens — who was campaigning in the east — and capitalizing on his blood connection to Julian. His reign lasted barely eight months before Valens crushed him in Phrygia in May 366. The usurpation was geographically compact, confined largely to the eastern Balkans and parts of Asia Minor, which means the minting window at Constantinople was short and output limited.

The REPARATIO FEL TEMP type was a deliberate borrowing from earlier Constantinian-era coinage, chosen to signal dynastic continuity with Julian's line rather than any genuine monetary reform.
