50 Centimes - Chambres de Commerce de Quimper et de Brest 29

When the Banque de France withdrew small-denomination coins from circulation during World War One — silver hoarded, bronze requisitioned for munitions — local chambers of commerce across France stepped in with paper emergency issues. The Quimper and Brest chambers pooled their authority under a joint issue, an administrative arrangement that was practical rather than common. Oberthur in Rennes, the dominant French provincial security printer of the period, handled the work. The series ran across multiple dated variants through 1922, well past the Armistice, because the coin shortage outlasted the war itself by several years.
