50 000 Mark

Herne's 50,000 Mark note is a product of the hyperinflation peak of 1923, when German municipal and regional authorities — Städte, Kreise, Handelskammern — were legally empowered to issue their own emergency currency, Notgeld, to compensate for the Reich's inability to keep denominations in meaningful circulation. By mid-1923, the Reichsbank simply could not print fast enough, and cities like Herne filled the gap with locally authorized paper.

Herne was a coal-mining industrial town in the Ruhr, then under French and Belgian occupation following Germany's default on reparations deliveries — a factor that complicated even routine commerce. The 50,000 Mark denomination, which would have seemed extraordinary months earlier, was already losing purchasing power by the week it was issued.
