Denier - Henri Ier et roi Henri IV

This denier was struck during one of the most combustible periods in medieval German ecclesiastical politics. The years 1067–1073 place it squarely in the run-up to the Investiture Controversy, when the relationship between the imperial throne and the German episcopate was fracturing under precisely the tensions that would culminate in Henry IV's humiliation at Canossa in 1077. The Bishopric of Speyer held particular significance to the Salian dynasty — Henry IV's father, Henry III, had lavished building patronage on Speyer Cathedral and was buried there.

The dual attribution to Henri Ier and roi Henri IV in the name reflects the overlapping authority structures of the period, with episcopal coinage rights bound tightly to royal confirmation.
