10 000 000 Mark

Ludwigsburg's municipal administration, like hundreds of German cities in the summer and autumn of 1923, was forced into the business of emergency currency simply to pay its own workers. By August of that year, hyperinflation was advancing so fast that the Reichsbank could not print or distribute notes quickly enough, and local authorities stepped in under official authorization to issue Notgeld denominated in figures that would have been unthinkable twelve months earlier. Ten million marks was not a large denomination by late 1923 standards — it was roughly bus-fare territory.

The embossed municipal seal served as the primary authentication device, a practical choice when speed of production mattered more than sophistication.
