50 Pfennig

Detmold's 1920 Notgeld issue belongs to the vast wave of municipal emergency currency that flooded Germany as small-change shortages became acute following the war. The Ratsdruckerei R. Dulce in Glauchau was a minor provincial printer that handled a number of these local contracts — not one of the prestige houses like Giesecke & Devrient, which tells you something about the budget and urgency involved.

The DeNG reference suffix ".8-9/10" indicates this note belongs to a multi-variety set, likely differentiated by serial number range or minor typographic variation — a common complication for collectors working through the Detmold issues.
