Pfennig 'Ewiger Pfennig'

The "Ewiger Pfennig" — Eternal Pfennig — takes its name not from poetic flourish but from a specific monetary reform: rather than periodic re-minting campaigns that forced subjects to exchange old coins at a loss, the issuing authority guaranteed indefinite legal validity. The Abbey of Saint Gall adopted this system as it spread through the Rhine and Lake Constance region during the late thirteenth century, sparing holders the recurring devaluation that conventional renewal cycles imposed.

Saint Gall's issues from this period occupy a narrow documentary window; the abbey's mint rights were perpetually contested by the town of Saint Gallen, which gained increasing autonomy throughout the fourteenth century.
