500 000 000 Mark Landkreis Bochum

One of hundreds of emergency currency instruments issued by German district administrations during the hyperinflation of 1923, this note from the Landkreis Bochum — the rural administrative district surrounding the city of Bochum, distinct from the city itself — reflects the point at which the Reichsmark had collapsed so thoroughly that half a billion marks was a denominations of practical, everyday necessity rather than theoretical abstraction. By the time notes at this level were being printed and distributed, the Reichsbank's own supply chain could not keep pace with demand, forcing Kreisausschüsse across the Ruhr to issue their own Notgeld.

The Ruhr occupation by French and Belgian forces, ongoing since January 1923, had strangled industrial output and accelerated the currency's collapse. Local authorities in the region were simultaneously administering passive resistance and managing monetary chaos.
