Tremissis - Moneyer Ansoaldus Metz mint

Metz was among the most productive Merovingian mints of the seventh century, and moneyers like Ansoaldus operated with considerable autonomy — striking in the king's name but effectively running what amounted to private coining operations under royal license. The tremissis was the workhorse denomination of Frankish long-distance trade during this period, particularly along the Moselle corridor connecting the Rhineland to Mediterranean commercial networks.

Belfort's cataloguing of this type in the late nineteenth century remains the foundational reference, though subsequent scholarship has complicated his attributions at several Austrasian mints.
