50 Centimes - Chambre de Commerce de Châlon-sur-Saône, Autun et Louhans 71

French chambers of commerce were authorized to issue emergency small-denomination notes from 1914 onward as the war drained metallic coinage from circulation almost immediately — silver and nickel disappeared fast, hoarded or melted. The Châlon-sur-Saône, Autun et Louhans chamber covered a notably fragmented commercial geography, spanning three distinct towns across the Saône-et-Loire, which was unusual for these regional issues and reflected pre-existing administrative arrangements rather than any wartime expedience.

B. Arnaud of Villeurbanne handled a considerable volume of these provincial emergency issues out of Lyon, and the watermark security was modest by design — adequate for local trust, not for forgery resistance at scale.
