50 Pfennig

Hachenburg's 1921 Notgeld issue is square — genuinely square, not just nearly so — which places it among the more deliberate format eccentricities of the German emergency money period. Most municipal issuers stuck to conventional oblong proportions; a 73 × 73 mm note required a specific decision, not a default.

G. Hunckel of Bremen handled a significant volume of Notgeld commissions during the early 1920s inflationary spiral, supplying small municipalities across northwest Germany that lacked access to larger printing houses. Hachenburg, a small Westerwald town in the Rhineland-Palatinate region, would have been exactly that kind of client.
