Nummus - Crispus as Caesar CAESARVM NOSTRORVM, Arelate

Crispus, Constantine's eldest son and a capable military commander who had recently distinguished himself defeating the Franks on the Rhine, was struck from the historical record entirely in 326 AD when his father ordered his execution — the reasons remain genuinely disputed, with ancient sources pointing variously to a plot alleged by his stepmother Fausta, who was herself killed by Constantine shortly afterward. Coins issued in his name were subject to damnatio memoriae, meaning surviving examples were actively removed from circulation and destroyed, which accounts for the relative difficulty of assembling a complete type series for his Caesarship issues.
