1 Franc - Chambre de Commerce de Nice et des Alpes Maritimes 06

France's wartime coin shortage pushed hundreds of regional chambers of commerce into issuing their own fractional notes between 1914 and the early 1920s — a stopgap tolerated by the state but never entirely comfortable with it. The Nice chamber's series was printed locally by Fortuné Robaudy of Cannes, a firm that handled a significant share of southern French emergency paper during this period.

Marius Simon's design credit is worth noting: he was a Niçois artist with municipal commissions to his name, and his involvement here was no accident — the chamber wanted something that read as regional rather than purely administrative.

The watermark security feature places this above the most rudimentary wartime issues, though counterfeiting of small-denomination nécessité notes was a persistent problem nationally.
