1 Pfennig - Heldrungen Gewerkschaft Heldrungen II

Gewerkschaft Heldrungen II was a coal mining cooperative operating in the Heldrungen district of Thuringia, one of dozens of small industrial operations that issued private zinc notgeld tokens when wartime metal shortages and Reichsbank restrictions left workers without small change. These mine-issued pfennig pieces circulated almost exclusively within the colliery's own payment system — company store purchases, wage adjustments — and rarely traveled far from the pit head.

Zinc was the material of last resort, prone to corrosion and difficult to strike cleanly, which explains why surviving examples in problem-free condition are consistently harder to locate than the mintage context would suggest.
