20 000 000 Mark Hennef

Hennef's municipal administration issued this 20,000,000 Mark note at the absolute peak of the Weimar hyperinflationary spiral — a point in mid-to-late 1923 when even denominations this large were functionally small change. The Rhenania-Druckerei in Bonn supplied notgeld to numerous Rhenish municipalities simultaneously, which is why the printing quality across these local emergency issues is relatively consistent despite the chaos of the period.

Bürgermeisterei Hennef was a minor administrative unit with no banking infrastructure of its own, issuing paper purely to keep local commerce moving when Reichsbank notes couldn't reach circulation fast enough to match price increases.
