100 000 000 Mark

Witten's 100-million Mark note is a product of the absolute peak of the German hyperinflation — by August 1923, municipal and regional authorities across the Reich were printing their own emergency currency, Notgeld, because the Reichsbank simply could not produce denominations fast enough to keep pace with collapsing purchasing power. The Stadtgemeinde issued this through a local press rather than any central authority, a purely practical decision driven by logistics and desperation.

Aug. Pott's Märkische Druckerei was a regional commercial printer, not a security printing house. Whatever anti-counterfeiting measures exist on this note are incidental to its design, not engineered — by this point in the crisis, forgery was barely a concern worth addressing.
