30 Pfennig M. A. Duer

Issued in 1920 during the plebiscite period that determined whether Schleswig would join Germany or Denmark, this Flensburg Notgeld piece comes directly out of one of the most politically charged moments in the region's modern history. The vote in Zone 1, which included Flensburg, returned a majority for Germany in March of that year — the notes circulated through exactly that moment of uncertainty.

Gebr. & Kunze printed locally, and Feddersen's design credit marks this as a genuinely regional production rather than the generic Notgeld series farmed out to Leipzig or Dresden jobbers. The watermark security feature is unusual for small-denomination Kleingeldersatz of this type.
