10 000 - Ouverture le jeu des entreprises

This is a corporate jeton de formation — a training banknote issued by Crédit Agricole de l'Yonne for use in business simulation exercises, not a circulating instrument of any kind. "Ouverture le jeu des entreprises" identifies it as a component of a structured management training game, a format popularised in French cooperative banking networks during the 1980s and 1990s to teach credit analysis and enterprise finance to branch staff.

No redemption value, no central bank authorization. Collectible primarily because regional Crédit Agricole caisses produced these independently, meaning designs varied by department and many were discarded after the training programs concluded.
