50 000 000 000 Mark

Aachen's municipal and district authority issued this 50-billion Mark note during the hyperinflation peak of late 1923, when German notgeld denominations were escalating so rapidly that printing plates became obsolete within days of use. Aachen sat in the occupied Rhineland under Allied administration at the time, which created an additional layer of bureaucratic peculiarity — local emergency currency had to function within a territory where the Reichsmark's authority was already compromised by both occupation policy and monetary collapse.

Printed locally by the Aachener Verlags- und Druckerei GmbH, the note was never intended to outlast the stabilization of November 1923, and it didn't.
