Denier anonymous

Vierzon's anonymous deniers fall within the loose monetary orbit of the Berry region, where minor lordships routinely struck in their own name — or, as here, in no name at all — throughout the twelfth century. The anonymity was not evasion but convention, a common practice among smaller feudal mints whose authority derived from custom rather than formal royal grant. The dating range spans nearly five decades, making die-linkage studies the only reliable tool for sequencing production within the series.
