1 franc Bon de solidarité

The Secours National was a French relief organization that predated Vichy but was co-opted by the regime after 1940, transformed into a tool of the National Revolution's social welfare apparatus. These solidarity vouchers — bons de solidarité — were not legal tender but functioned as quasi-currency in charitable distributions, issued to fund relief efforts during the Occupation years when conventional fiscal channels were constrained by German armistice demands.

The 1 franc denomination is the most commonly encountered in the series. Small face values circulated heavily through welfare networks and survive in quantity, though the fragility of the stock means genuinely uncirculated examples are harder to find than their abundance suggests.
