4 Reichspfennigs Metallwerke Holleischen

Metallwerke Holleischen was a forced-labor armaments factory operating within the Holýšov concentration camp complex in the Protectorate of Bohemia and Moravia. The plant, a subsidiary of Dynamit AG, produced shell casings and precision munitions components using prisoner labor drawn from the camp's population, which included Jewish women transferred from Auschwitz in 1944. These Lagergeld denominations were issued as internal camp scrip — not wages in any meaningful sense, but a control mechanism regulating access to whatever marginal goods the camp administration permitted prisoners to purchase.

The yellow cardboard stock is characteristic of the series. Survival rate is relatively low given the circumstances of the camp's liberation in May 1945.
