50 000 000 Mark

Sterkrade was an industrial city in the Ruhr, and its municipal notgeld issues of 1923 came directly out of the occupation crisis — French and Belgian forces had seized the region in January of that year, and the resulting passive resistance campaign collapsed normal currency supply chains. Local authorities across the Ruhr printed their own emergency denominations to keep wages and commerce moving as Reichsbank notes became both scarce and instantly obsolete.

The fifty-million mark face value places this note squarely in the hyperinflation peak of mid-to-late 1923, when denominations of this magnitude were still insufficient for a week's groceries. Sterkrade was absorbed into the newly created city of Oberhausen in 1929, so the issuing authority ceased to exist entirely within six years of this note's printing.
