1 Franc Fluquières

Fluquières is a village of a few hundred inhabitants in the Aisne département — the sort of place that would never appear in a banknote catalog under ordinary circumstances. It does so here because the German occupation of northern France in 1914–15 severed local communities from the French monetary system almost entirely, forcing hundreds of communes to print their own fractional emergency notes to keep small transactions functioning. The Imprimerie du Guetteur in Saint-Quentin, itself operating under occupation, supplied many of these issues across the region.

The official stamp is the sole security measure, which tells you everything about the trust model: these notes worked because refusal was impractical, not because forgery was difficult.
