50 centimes - Chambre de Commerce de Chalon-sur-Saône, Autun et Louhans [71]

The Chambres de Commerce emergency issues of 1916 were a direct response to the acute small-change shortage that swept France once wartime hoarding stripped silver from circulation almost entirely. This chamber covered three distinct commercial centers — Chalon-sur-Saône, Autun, and Louhans — an unusually wide geographic remit for a single issuing authority, reflecting the administrative consolidation forced on the region by wartime staffing constraints.

B. Arnaud's Lyon workshop handled a significant volume of these regional nécessité notes during the war years, and the watermarked paper was one of the few anti-counterfeiting provisions available at a moment when sophisticated security printing was simply not a priority.
