Denier - Charlemagne Strasbourg mint

This issue predates Charlemagne's monetary reform of 793–794, which scrapped the lighter Merovingian weight standard and imposed the new heavy denier of roughly 1.7g across the empire — making coins of this earlier type obsolete almost overnight. The Strasbourg mint, known in Carolingian documents as Argentoratum, was one of the few Rhenish mints active through the full arc of this pre-reform period. Surviving examples attributable to Strasbourg from these years are considerably scarcer than output from the major palace mints at Melle or Paris.
