10 Pfennig - Halle an der Saale Hallesche Pfännerschaft A.G.

The Hallesche Pfännerschaft was a salt-production cooperative in Halle with roots stretching back to medieval guild structures — the Pfänner being the salt-pan operators who controlled the saline springs along the Saale. This notgeld issue emerged during the 1917–1921 zinc coinage crisis, when wartime metal shortages forced German municipalities and private enterprises to produce their own emergency currency. Zinc was one of the few workable substitutes available, though it corrodes aggressively, which explains why survivors in clean condition are less common than mintage figures might suggest.
