50 Dollars - F.E.C. School Bank Montreal, Quebec

F.E.C. — almost certainly the Frères des Écoles Chrétiennes, the French-language Catholic teaching order known in English as the De La Salle Brothers — operated school banking programs across Quebec in the early twentieth century as a tool for teaching children savings habits. These scolaire notes were not legal tender and carried no redemptive value outside the classroom ledger system; they circulated only within the school's internal economy, awarded for academic performance or deposited into mock accounts.

Survival rate is surprisingly low. Paper this thin, handled by children and stored in desks, rarely lasted beyond a single school year.
