1 000 000 Mark Hugo Stinnes Linien

Hugo Stinnes Linien was one of the commercial shipping and industrial combines that issued its own emergency currency — Notgeld — during the hyperinflation peak of 1923, when the Reichsbank simply could not keep pace with denomination demand. Private firms, municipalities, and even transit companies printed their own notes as a practical necessity, not as a monetary experiment. Stinnes himself was the most powerful industrialist in Weimar Germany at the time, controlling coal, steel, shipping, and press holdings simultaneously.

The watermarked paper is notable — most corporate Notgeld at this denomination level dispensed with security features entirely, making the inclusion here unusual for a private issuer.
