500 000 000 Mark

Vohwinkel was a small industrial town on the eastern edge of Wuppertal — then not yet formally consolidated into the larger city — and like hundreds of German municipalities in late 1923, it was forced to issue its own emergency currency simply to meet payroll. The half-billion mark denomination tells you exactly where this note sits in the hyperinflation timeline: by October and November 1923, the Reichsmark was losing value faster than notes could be printed and distributed, and local authorities were issuing new denominations within days of the last series becoming functionally worthless.

Notgeld of this period was typically produced by regional printers on short contracts, often on whatever paper stock was available — quality control was not the priority.
