Nummus - Crispus CAESARVM NOSTRORVM VOT X, Rome

Crispus, Constantine's eldest son by his concubine Minervina, was elevated to Caesar in 317 and spent the early 320s commanding the Rhine frontier with considerable success — most notably the naval engagement on the Hellespont in 324 that effectively broke Licinius's fleet. The VOT X vows celebrated here anticipated a decade of rule that never materialized. In 326, Constantine ordered Crispus executed at Pola; the reasons remain historically opaque, with ancient sources offering rumors of adultery with his stepmother Fausta rather than documented conspiracy. His name was subsequently struck from inscriptions across the empire.
