1 Franc - Chambre de Commerce de Lons-le-Saunier 39

Lons-le-Saunier is the prefecture of the Jura department, and like hundreds of French Chambers of Commerce after World War One, it continued issuing small-denomination emergency paper well into the 1920s — long after the immediate postwar coin shortage that originally justified the practice. By 1925 the French Treasury had largely restored metallic circulation, making this franc note something of a bureaucratic holdover rather than a genuine necessity. The Grands établissements de l'imprimerie générale in Grenoble handled a substantial share of provincial Chamber issues across southeastern France during this period, and their output is generally consistent in production quality.
