50 000 000 000 Mark

Kreisamt Bingen was one of hundreds of German district and municipal authorities that resorted to printing their own emergency currency — Notgeld — during the hyperinflationary collapse of 1923. By the time fifty-billion-mark denominations became necessary, the Reichsbank's own presses could not keep pace with the devaluation. Local printers like Vincenz Pekarek, operating out of Bingen am Rhein, were pressed into service to fill the gap.

Pekarek was a local commercial printer, not a security printing house. The absence of specialized anti-counterfeiting measures was largely irrelevant by this point — the notes depreciated faster than anyone could profitably forge them.
