20 Kreuzers - Adalbert II of Walderdorff

Adalbert II von Walderdorff served as Prince-Bishop of Fulda from 1757 until his death in 1759 — making this a terminal-year issue from an episcopate that lasted barely two years. Fulda's coinage rights derived from its ancient imperial abbey status, confirmed repeatedly by the Holy Roman Emperors, and the mint remained active through the Seven Years' War, which was actively reshaping central German territories when this piece was struck.

The .583 fineness is notably below the Reichsthaler standard, reflecting the wartime monetary degradation common to smaller German ecclesiastical mints after 1756.
