50 Pfennig

Lüben was a small Silesian market town — precisely the kind of municipality that found itself issuing its own emergency currency in 1919 when the postwar coin shortage left ordinary commerce at a standstill. Germany's Kleingeldersatz problem was national in scale, and hundreds of towns like Lüben filled the vacuum with locally authorized Notgeld before the Reichsbank could stabilize small denomination supply.

L. Fernbach of Bunzlau, roughly 30 kilometers away, was a regional printer serving the Silesian trade rather than a specialist banknote firm — a detail that places this squarely in the improvised end of the Notgeld spectrum. The suffix "c" in the DeNG reference indicates a distinct variety within the L70.4 type, likely a color or paper variant.
