10 Pfennig - Pforzheim Kollmar and Jourdan A.G.

Kollmar & Jourdan was one of Pforzheim's prominent jewelry and metalware manufacturers, and like dozens of German industrial firms in 1916, it was pressed into service as an emergency currency issuer when the Imperial government's wartime metal requisitions gutted the normal coin supply. Zinc was the compromise material — iron was militarily essential, copper increasingly so, and the traditional silver and nickel coinage had long since vanished into hoarding and melting.

Pforzheim's notgeld issues from this period are unusually well-documented by Menzel's reference catalogs, which is why two distinct catalog numbers exist for variants within this type.
