Regensburg,Wandalgarius and the novi denarii: Charlemagne's monetary reform revisited

Until now, Philip Grierson's tentative dating of Charlemagne's monetary reform to 793/4 has been generally accepted. His dating was based not only on numismatic evidence but also on his attempt to set this event in the context of Charlemagne's activities from 792 to 794. This traditional date of the reform does not, however, take into account evidence provided by Codex Sangallensis 731, in which the scribe Wandalgarius drew the image of a post‐reform coin around mid‐October 793. Based on this evidence as well as the historical contextualization of Charlemagne's stay in Regensburg in 791–3, this paper attributes the introduction of the novi denarii to the period between the autumn of 792 and the early autumn of 793, when his court was located in Regensburg.
