Numismatics
Byzantine coinage was in use in Francia before Theudebert I began minting his own money at the start of his reign. He was the first to issue distinctly Merovingian coinage. On gold coins struck in his royal workshop, Theodebert is shown in the pearl-studded regalia of the Byzantine emperor; Childebert I is shown in profile in the ancient style, wearing a toga and a diadem. The solidus and triens were minted in Francia between 534 and 679. The denarius (or denier) appeared later, in the name of Childeric II and various non-royals around 673–675. A Carolingian denarius replaced the Merovingian one, and the Frisian penning, in Gaul from 755 to the 11th century.
Merovingian coins are on display at the Monnaie de Paris in Paris; there are Merovingian gold coins at the Bibliothèque Nationale, Cabinet des Médailles.
