5 Pesos Plata Boliviana

The Banco Argentino operated out of Concordia, Entre Ríos — a provincial river town whose commercial importance derived almost entirely from its position on the Uruguay River and cross-border trade with Uruguay itself. That geography explains the denomination: pesos plata boliviana was the de facto trading currency across much of the Río de la Plata interior in the 1870s, preferred over Buenos Aires paper by merchants who didn't trust provincial emissions.

ABNC produced the plates in New York under contract during a period when virtually every Argentine provincial bank went to American or British security printers — domestic printing capacity simply didn't exist at the required security standard. The Banco Argentino itself was short-lived, and PS#1460 survivors are genuinely rare.
