50 Pfennig - Schroda

Schroda — known today as Środa Wielkopolska in west-central Poland — was under Prussian administration when this piece was issued in 1917, the deepest point of Germany's wartime metal shortage. Municipal authorities across the Reich were authorizing local emergency coinage that year as copper, nickel, and brass were requisitioned for the war effort. Zinc was the compromise material: abundant, workable, but prone to corrosion, which explains the multiple catalogue variants recorded under the Menzel references — surface degradation and striking inconsistencies between dies were common enough to generate distinct collectible types from a single issue.
