1 000 000 Mark overprint on 100 Mark

Schneidemühl — now Piła in northwestern Poland — was one of dozens of German municipalities forced to print their own emergency currency during the hyperinflation of 1922–1923, as the Reichsbank simply could not produce notes fast enough to keep pace with collapsing purchasing power. The solution here was brutally practical: existing 100 Mark Reichsbank notes were overprinted by the Stadtkasse and reissued at a face value ten thousand times higher.

The overprint itself is the note's entire story. By the time this denomination made sense, it was already obsolete within weeks.
