1 000 000 Mark Sobernheim

Sobernheim is a small town in the Nahe valley, and like hundreds of German municipalities in 1923, it issued its own emergency currency — Notgeld — when the Reichsbank's hyperinflationary collapse made official denominations functionally useless within weeks of printing. The one-million Mark face value, staggering on its face, was already borderline inadequate by the time most such notes reached circulation that summer and autumn.

Municipal Notgeld of this period was typically printed locally on whatever stock was available, which accounts for the wide variation in paper quality and ink stability seen across survivors.
