5 000 000 Mark

Sonneberg was a major toy manufacturing center in Thuringia, and by August 1923 the hyperinflation had accelerated so far beyond the Reich's printing capacity that municipalities were legally authorized to issue their own emergency currency — Notgeld — to meet weekly payroll. The Stadtkasse (municipal treasury) was the issuing body, not a private bank or chamber of commerce, which gave these notes a quasi-official standing within the town.

Five million marks sounds extraordinary, but by the time this note circulated it bought roughly what a few pfennigs had purchased four years earlier. Within weeks of issue, denominations like this were already obsolete.
