1 Franc CDC Constantine

Constantine's Chambre de Commerce issued these francs as local emergency currency after the outbreak of war drained metallic coin from circulation across French Algeria — a problem common to chambers of commerce throughout the empire and metropolitan France alike during this period. Waton's press in Saint-Étienne supplied a number of similar emergency issues to provincial issuers, making the printing origin unremarkable, though the Algerian colonial application is less frequently discussed.

The JP# reference covers an unusually wide spread of variety numbers, indicating significant typographic and date variation across the 1915–1918 window. Collectors should distinguish carefully between these variants, as relative scarcity differs sharply across the sequence.
