4.2 Pfennig Gold = 1⁄100 US-Dollar Flensburger Schiffbaugesellschaft

During the hyperinflation crisis of 1923, when the Reichsmark was collapsing daily, German businesses issued their own emergency currency — Notgeld — to keep payrolls and local commerce moving. The Flensburger Schiffsbaugesellschaft, a major shipyard on the Flensburg Fjord, denominated this note not in Marks but in Goldpfennig pegged to the US Dollar, an explicit acknowledgment that the national currency had become worthless as a unit of account.

The printer, Deutscher Verlag — the commercial arm of the local newspaper Flensburger Nachrichten — was a practical choice of proximity, not prestige. The watermark security feature is notable for a private industrial issuer at this scale.
