Nummus - Crispus CAESARVM NOSTRORVM, Treveri

Crispus, Constantine's eldest son by his concubine Minervina, was elevated to Caesar in 317 and proved himself a genuinely capable commander — his decisive naval victory over Licinius at the Hellespont in 324 was instrumental in his father's final consolidation of sole rule. Within two years of that triumph, Constantine had him executed at Pola, the reasons still debated: conspiracy, rivalry, or the intervention of his stepmother Fausta, who was herself killed shortly after. Treveri, one of the great western mints of the Tetrarchic and Constantinian periods, issued this nummus in the narrow window before that dynastic rupture made Crispus coinage politically inconvenient to hold.
