50 Pfennig Altdeutscher Keller

Wyk auf Föhr is a small resort town on the North Frisian island of Föhr, and this 50 Pfennig note is a piece of Notgeld issued by the Altdeutscher Keller — a restaurant, not a municipal authority. Private commercial establishments issuing their own emergency currency during the 1920s inflation period was not unusual in Germany, but a restaurant-issued note with a named designer is a cut above the typical hastily printed scrip of the era.

Hans Westerwald's credit on a piece of this scale suggests the note was produced as much for the collector market as for actual change-making use — a common commercial reality for Serienscheine by 1921–1922.
