1 Franc / 80 Pfennig

When German forces occupied Luxembourg in August 1914, the existing note supply became immediately inadequate. The État du Grand-Duché responded by issuing this emergency series, and the dual denomination — one franc and eighty pfennig simultaneously on the same note — was a direct concession to the occupation: the pfennig equivalent acknowledged the German monetary system now effectively running alongside Luxembourg's own.

Giesecke & Devrient had long-standing relationships with smaller European states for exactly this kind of urgent small-denomination work. The Leipzig connection here carries an uncomfortable irony: the note's printer was headquartered in the same country whose army had just crossed the border.
