1 Gold Pfennig Flensburger Goldmarkgesellschaft

The Flensburger Goldmarkgesellschaft was a private issuing entity operating out of Flensburg during the Rentenmark stabilization period, when confidence in state-backed currency remained fragile enough that regional and commercial goldmark schemes found a genuine market. The "Gold Pfennig" denomination is exceptionally small — fractional goldmark scrip at this scale was issued by very few private entities, and Flensburg's geographic position as a border city freshly partitioned from Denmark by the 1920 plebiscite gave local commerce a particular incentive to anchor exchange in something metal-referenced.

The m.b.H. corporate structure suggests a limited-liability trading consortium rather than a bank, though the precise membership of the Gesellschaft is not widely documented.
