50 Centimes - Chambre de Commerce de Roanne 42

French chambers of commerce were authorized to issue emergency small-denomination paper money in August 1914, almost immediately after mobilization stripped the country of coined silver and copper. Roanne's chamber was among the earliest provincial issuers, and the 50 centimes notes appeared in 1915 as the coin shortage showed no sign of resolving. These issues circulated locally as a matter of practical necessity — not monetary policy from Paris, but a stop-gap organized at the departmental level.

The JP reference covers four distinct varieties under a single type, differentiated by serial letter combinations and minor typographic changes across printings by Bourg et Cie.
