Antoninianus - Tetricus II COMES AVG

Tetricus II was elevated to Caesar by his father Tetricus I around 272, a political move designed to legitimize a dynasty that had controlled the breakaway Gallic Empire for less than a decade. The joint reign lasted only until 274, when Aurelian crushed the Gallic forces at the Battle of Châlons and reintegrated the western provinces into Rome. COMES AVG — "companion of the Augustus" — was an honorific applied to the Caesar in recognition of his subordinate but elevated status.

Billon coinage of the Tetrici is notorious for its debased silver content, sometimes barely registering above bronze.
