1 Pfennig - Heddernheim Kupfer Werk

Heddernheimer Kupferwerk, a copper and metal goods manufacturer in the Frankfurt suburb of Heddernheim, issued notgeld pfennig pieces during the acute small-change shortage that gripped Germany in the early 1920s. Industrial firms commonly issued their own emergency coinage redeemable at company facilities when municipal and state supplies dried up. The irony of a copper works issuing zinc rather than copper tokens likely reflects wartime and postwar metal allocation restrictions that lingered well into the early Weimar period.
