25 Centimes

Marengo — renamed from the Berber settlement of Hadjout by French colonial authorities — issued emergency small-change notes during World War One because the wholesale hoarding of coins had left Algerian municipalities functionally without fractional currency. The Chambre de Commerce d'Alger coordinated many such issues across the département, but individual communes also issued independently, which is why Marengo's notes carry the municipal authority rather than a regional body.

These hyper-local Algerian necessity issues from 1914–1918 are poorly documented compared to their metropolitan French counterparts, and survival rates are uneven. Marengo's 25 centimes is among the more obscure entries in the series.
