50 000 000 Mark

Solingen printed its own emergency currency during the hyperinflation of 1923 — this 50 million Mark note is a product of the Notgeld system, in which German municipalities were legally permitted to issue their own paper money when the Reichsbank could no longer supply denominations large enough for everyday transactions. By mid-1923, that figure of 50 million was itself obsolete within weeks of printing.

Hermann Rabitz was a local commercial art printer, not a security printing house. That distinction matters: Notgeld from municipal printers like Rabitz was produced without sophisticated anti-counterfeiting measures, relying instead on rapid denomination obsolescence as its primary deterrent.
