100 lei Fondul Social

Romanian consumer cooperatives issued their own internal scrip throughout the communist period, functioning as a parallel exchange medium within the cooperative retail network rather than as state legal tender. These "Fondul Social" notes — Social Fund notes — were tied to cooperative membership contributions and could be redeemed against goods or services within the system, effectively binding workers to cooperative commerce rather than open-market spending.

The thirteen-year span of this issue without design change reflects the rigid standardization imposed on cooperative institutions under Gheorghiu-Dej's administration. Attribution of exact print runs remains difficult; Romanian cooperative scrip was poorly documented compared to National Bank emissions, and survival rates are low partly because members had strong incentive to spend rather than hold them.
