10 Gulden Danziger Zentralkasse

The Danziger Zentralkasse was established specifically to handle the Free City of Danzig's acute currency instability during the early 1920s hyperinflationary period — a political entity with its own monetary system, sandwiched between Germany and Poland, neither of which it belonged to. The 1923 date places this note squarely in the worst of that regional chaos, when Danzig's Gulden was being actively managed to avoid the collapse engulfing the German Reichsmark across the border.

The watermark security on a note of this period and region is worth noting — many contemporaneous emergency issues dispensed with such features entirely under production pressure.
