1 Tremissis In the name of Anastasius I, Lyon

The Burgundian kingdom occupied an awkward political position in late 5th-century Gaul — nominally federate allies of Rome, then subjects of the Eastern Empire, yet effectively autonomous under Gundobad. Striking tremisses in Anastasius's name was a deliberate act of legitimacy-borrowing: the Burgundians lacked the authority to issue coinage in their own right and instead sheltered under imperial iconography while running their own mint at Lyon, one of the most active post-Roman minting centers in the West.

Lyon's output for this type is documented across several die groupings in Tomasini's classification, with the A5 group showing consistent fabric characteristics that distinguish it from contemporary Visigothic and Frankish imitations of the same imperial prototype.
