1 Pfennig - Oberhausen PoW Camp Hansfield Limestone Quarry

Prisoner-of-war camp scrip from German-occupied or German-administered facilities in World War I served a specific administrative function: keeping captive labor paid in currency unusable outside the wire. The Hansfield Limestone Quarry at Oberhausen was a working industrial site, and notes like this were issued as wages to prisoners assigned to quarry labor — a practice that technically complied with the Hague Convention's requirement that prisoners be compensated while simultaneously ensuring no value could leave the facility.

Camp scrip at this scale of denomination is among the most perishable printed material of the war. Few examples survive from quarry operations specifically.
