5 000 000 Mark Kreis Rügen

Bergen auf Rügen was one of hundreds of German county administrations forced to print emergency money during the hyperinflation of 1923, when the Reichsbank simply could not produce currency fast enough to keep pace with collapsing purchasing power. Kreis Rügen's five-million-mark note arrived at a moment when that denomination, staggering by any peacetime measure, would within weeks be rendered worthless by further inflation — the Rentenmark stabilization in November 1923 ended the entire Notgeld episode almost overnight.

County-level issues like this one were printed locally and often in small runs, which makes surviving examples genuinely scarcer than their municipal counterparts from larger cities.
