1 Peso Plata Boliviana

Banco Argentino operated out of Paraná, capital of Entre Ríos province, during the brief window of provincial free banking that preceded Argentina's slow consolidation of monetary authority. This note, denominated in pesos plata boliviana, reflects the practical reality of the Río de la Plata interior, where Bolivian silver coinage — not Argentine — was the dominant circulating specie and the natural reference unit for commercial paper.

ABNC produced the plates in New York, as they did for dozens of Latin American provincial banks in the 1860s. The PS# series prefix confirms this is catalogued under Argentine private and provincial bank issues — a category where surviving examples are genuinely uncommon, Entre Ríos issues especially so.
