Nummus - Constantine I MARTI CONSERVATORI with T F, Treveri

The MARTI CONSERVATORI series from Treveri reflects Constantine's deliberate cultivation of Sol Invictus and Mars as divine patrons during the years immediately following his break with Maximian in 310 — a political rupture that ended in Maximian's forced suicide at Marseille. The T F mintmark places this piece among the officina outputs that ramped up sharply as Constantine consolidated the Rhine frontier and prepared for the civil wars that would ultimately end at Milvian Bridge.

RIC VI 854 is not a common variety. Treveri was Constantine's principal western mint during this period, and attribution of individual officina letters remains the primary means of sequencing production across what was an unusually compressed three-year window.
