1 Pfennig - Dresden Dyckerhoff & Widmann A.G.

Dyckerhoff & Widmann was one of Imperial Germany's most technically ambitious construction firms, responsible for pioneering reinforced concrete construction — their projects included early ferro-concrete bridges and industrial halls that pushed the limits of the material. Like many large industrial employers of the Wilhelmine and Weimar periods, the Dresden works issued zinc notgeld pfennigs for internal canteen or payroll use, a practice that sidestepped chronic small-change shortages without requiring Reichsbank authorization. The zinc composition reflects wartime or postwar metal economies rather than any permanent monetary intent.
