5 Pfennig - Elberfeld

Elberfeld issued iron notgeld in 1917 under the same wartime metal shortages that stripped copper and nickel from circulation across Germany — by that point, both metals had been requisitioned for armaments production, forcing municipalities to improvise with whatever the central government hadn't yet claimed. Elberfeld itself would cease to exist as an independent city less than a decade later, absorbed into the newly consolidated Wuppertal in 1929.
