50 000 Mark

Siegburg's 50,000 Mark Notgeld was issued during the hyperinflation acceleration of 1923, when municipal and commercial authorities throughout the Rhineland were printing emergency currency faster than the Reichsbank could supply legal tender. Gebr. Daemisch was a local print shop, not a specialist banknote printer — which is exactly what you would expect from a city of Siegburg's modest size scrambling to keep small transactions functioning.

The Rhineland occupation by Allied forces complicated matters further: French and Belgian troops controlled the region, and the economic disruption of the Ruhr occupation beginning in January 1923 accelerated the collapse that made notes like this one obsolete within months of printing.
