Nummus - Crispus PRINCIPIA IVVENTVTIS, Thessalonica

Crispus was elevated to Caesar in March 317 alongside his half-brother Constantine II and cousin Licinianus, a political settlement brokered after Licinius's defeat at the Battle of Cibalae. The Thessalonica mint responded quickly, issuing the PRINCIPIA IVVENTVTIS type as a public declaration of dynastic continuity — Crispus as heir presumptive to the western throne. He would go on to prove himself the ablest general of his generation before Constantine had him executed at Pola in 326, for reasons that ancient sources conspicuously refused to explain.
