Neuenbürg's iron notgeld emerged from the acute metal shortages that paralyzed German municipal finances in the final year of the First World War, when copper and nickel had long since been redirected to shell casings and industrial war production. District-level authorities across Württemberg were left to improvise, issuing locally sanctioned emergency coinage with no central design standard — which is precisely why Oberamt pieces vary so dramatically between neighboring districts.
Iron was a poor substitute: it corrodes readily, and surviving examples in clean condition are harder to find than the mintage figures alone would suggest.
