Denier - Sede Vacante

Sede vacante coins were struck during the vacancy between episcopal appointments, when cathedral chapters exercised temporary temporal authority. The Lausanne bishopric occupied a strategically contested position between Burgundian and imperial spheres, and the right to coin during vacancies was itself a jealously guarded prerogative — one that Holy Roman emperors periodically challenged throughout the eleventh century.

HMZ 1#1-485a is among the earliest documented Lausanne deniers, predating the fuller episcopal series that emerges under confirmed bishops later in the century.
