50 Centimes - Chambre de commerce d'Annonay [07]

Annonay, a small industrial town in the Ardèche, had outsized importance in French paper manufacturing — the Montgolfier family, whose mills operated there, supplied much of the paper used in French banknote production. The local chambre de commerce issued these fractional notes during the acute coin shortage that followed France's wartime metal requisitions, a problem that forced hundreds of provincial chambers across France to produce their own emergency currency between 1914 and the early 1920s.

B. Arnaud of Villeurbanne handled a significant volume of such regional emergency issues for the Rhône-Alpes area. The JP reference numbers here span multiple dates and variants within the series, suggesting the chamber returned to press several times across the issue period.
