50 Pfennigs - Ruppersdorf Chamottefabrik

Chamotte — refractory fireclay — was a critical industrial material during the First World War, and factories producing it were classified as essential war industries. Ruppersdorf's Chamottefabrik issued notgeld like this piece when the Imperial government's metal requisitions and small-change shortage made conventional coinage effectively unavailable to factory workers receiving wages. Iron was the unsentimental solution: abundant, cheap, and increasingly unpopular in circulation due to rust and weight.

The Hasselmann reference places this firmly within the catalogued Saxony factory notgeld issues, a category where survival rates vary sharply by issuer size.
