25 Pfennig - Oberwesel

Oberwesel's 1919 iron notgeld was struck amid the acute metal and currency shortages that followed Germany's defeat, when municipal authorities across the Rhineland were left to improvise their own circulating money as the central monetary system buckled. The Rhineland itself was under Allied occupation by this point, adding a particular administrative friction to any official currency supply.

Iron was the default emergency material for dozens of German municipal issues in this period — not chosen for durability but because it was simply what was available after wartime requisitioning had stripped conventional coinage metals.
