10 Pfennig - Boppard

Boppard's 1919 iron notgeld issue belongs to the first wave of municipal emergency coinage that flooded the Rhineland as the German imperial monetary system collapsed following the armistice. The city, sitting on the Rhine between Koblenz and Bingen, had no special claim to early issuance — dozens of towns its size did the same. Iron was the only practical option; copper and nickel had been consumed by the war effort years earlier, and the central government had no capacity to supply smaller denominations to municipalities scrambling to make change.
