0,25 Mess d'Avord 18

Mess d'Avord was the canteen or officers' mess facility at the Avord military aviation camp in the Cher département — one of France's earliest and most significant military airfields, established before the First World War and heavily expanded during it. Small-denomination scrip of this kind was issued internally to manage canteen transactions without drawing on official coinage, which was badly hoarded across France from 1914 onward as the metal disappeared from circulation almost overnight.

The JP reference places this in Émile Joany and Claude Pirot's census of French necessity money, but documentation on Avord mess issues remains sparse. The fractional value — a quarter of whatever local unit applied — suggests this was the smallest denomination in the series.
