20 000 000 Mark Kreis Wipperfürth

Kreis Wipperfürth was a rural administrative district in the Bergisches Land region of the Rhine Province, and like hundreds of similar Kreise across Weimar Germany, it issued its own emergency currency during the hyperinflation of 1923 when the Reichsbank simply could not print fast enough to meet demand. By the time denominations reached the tens of millions of marks, the notes were losing purchasing power faster than they could be distributed — a 20,000,000 Mark note would have bought a loaf of bread at best, and only briefly.

The Rentenmark stabilization of November 1923 rendered the entire series worthless within weeks of issue.
