5 Pesos Fuertes

Banco Nacional operated as Argentina's first nationally chartered bank, established in 1872 under President Sarmiento. The institution lasted barely a decade before failing in 1876 amid a severe financial crisis that swept through the River Plate region — meaning notes from this 1873 issue circulated for an extraordinarily brief window before the bank collapsed and redemption became uncertain.

ABNC's involvement was typical for South American issuers of this period who lacked domestic intaglio capacity. The PS prefix in the Pick catalog places this firmly in the specimen or private bank category, and genuine circulated examples are genuinely hard to locate given the bank's short lifespan and the chaos surrounding its closure.
