Byzantine coinage was in use in Francia before Theudebert I began minting his own money at the start of his reign. 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 eleventh century.

The denarius subsequently appeared in Italy issued in the name of Carolingian monarchs after 794, later by so-called "native" kings in the tenth century, and later still by the German Emperors from Otto I (962). Finally, denarii were issued in Rome in the names of pope and emperor from Leo III and Charlemagne onwards to the late tenth century.
