The Chambres de Commerce across French Algeria were authorized to issue emergency fractional notes during World War One to address a severe shortage of small coinage — silver and bronze having effectively vanished from circulation as hoarding accelerated after 1914. Constantine's chamber was one of several Algerian commercial bodies that turned to local printers rather than metropolitan France, a practical necessity given wartime shipping constraints.

Imprimerie Adolphe Jourdan was Algiers' most established printing house, responsible for a significant volume of official Algerian administrative printing. That it handled emergency currency for multiple chambers is unsurprising; what is notable is how rudimentary the security features remained across the entire local issue series, a vulnerability nobody seriously exploited.
