Denier - Charlemagne Tiel mint

This denier predates Charlemagne's monetary reform of 793–794, which scrapped the lighter Merovingian weight standard and mandated a heavier penny of roughly 1.7g — making coins of this earlier type physically distinct from everything that followed. Tiel, on the Waal river, functioned as a commercial crossing point into Frisian trading territory, and its mint output during this phase reflects the empire's still-fragmentary monetary infrastructure before the reform imposed uniformity across the realm.
