10 Pfennig - Hildesheim Senkingwerk A.G.

Senkingwerk A.G. was a major metalware manufacturer in Hildesheim whose factory-issued notgeld filled the acute small-change shortage that gripped German industry in the early 1920s. Large employers frequently issued their own token coinage redeemable at company facilities, bypassing a municipal money supply that had effectively collapsed. Zinc was the practical choice — cheap, available, and already familiar to a metalworks operation.

Senkingwerk survived into the postwar decades as a producer of household goods before eventually closing.
