Nummus - Crispus BEATA TRANQVILLITAS, Treveri

Crispus, Constantine's eldest son by his concubine Minervina, was at the peak of his political standing in 321 — celebrated co-Caesar, recent victor over the Alemanni on the Rhine frontier, and widely seen as heir apparent. The Treveri mint sat in his administrative territory, and the BEATA TRANQVILLITAS issues of this year functioned partly as propaganda for his governance of the western provinces. Within five years, Constantine had him executed at Pola, the official record expunged so thoroughly that coins like this one are among the more tangible evidence of his existence.
