100 000 000 Mark Schorndorf; Bankhaus Carl Hahn

Bankhaus Carl Hahn & Co. was a private commercial bank operating out of Schorndorf, a small Württemberg town southeast of Stuttgart. Like hundreds of similar regional institutions during the hyperinflation peak of 1923, it was authorized under emergency provisions to issue Notgeld denominated in the astronomical figures that had become routine by mid-year. A 100-million-Mark note, incomprehensible a decade earlier, was by August 1923 barely sufficient for a loaf of bread.

Private bank issues of this magnitude are notably scarcer than municipal Notgeld from the same period — fewer were printed, distribution was narrower, and institutional collapse or merger often meant remaining stocks were never formally redeemed.
