Light Denier - Frederick I Annweiler

Frederick Barbarossa was granted the title of Duke of Swabia before his election as emperor in 1152, and Annweiler — a small imperial town in what is now Rhineland-Palatinate — fell within his direct Swabian holdings. Deniers struck there during his reign reflect the extreme fragmentation of minting authority in the medieval empire, where dozens of local workshops operated under loose imperial sanction rather than centralized control.

The low silver content and minimal weight of these issues were not degradation but design — light deniers circulated alongside heavier regional pfennigs in a deliberately tiered local economy.
