25 Pfennig - Haan

Haan's 1917 emergency coinage was part of the broader German Notgeld response to wartime metal shortages, as nickel and copper were diverted wholesale to military production. Municipal authorities across the Reich were left to improvise, issuing locally sanctioned substitutes of wildly varying quality. Zinc was the unsentimental solution for dozens of small Westphalian towns.

The nickel-plated variant catalogued under Funck#182.1 suggests the city made at least two production runs or surface treatments — a small distinction that collectors of German civic emergency issues track closely.
