Nummus - Constantius Gallus as Caesar Γ* / FEL TEMP REPARATIO, Thessalonica

Constantius Gallus was appointed Caesar by his cousin Constantius II in 351, partly to manage the volatile eastern frontier while the Augustus dealt with the usurper Magnentius in the west. The appointment was always uneasy. Gallus governed from Antioch with increasing brutality — executing officials and fomenting street violence — until Constantius summoned him west in 354 and had him beheaded near Pola before he reached thirty years old. His coinage accordingly spans a narrow four-year window.

Thessalonica's workshop used the Γ* officina mark for this issue, placing it within a well-documented RIC sequence for the mint under Gallus's brief Caesar tenure.
