50 Pesos Plata Boliviana

The Banco Argentino operated out of Paraná, capital of Entre Ríos province, during a period when Argentine provincial banking was largely unregulated and dozens of private institutions issued their own notes against dubious reserves. This 50 Pesos Plata Boliviana denomination reflects the practical reality of the Río de la Plata region's monetary confusion in the early 1870s — the Bolivian peso fuerte circulated widely enough in the interior provinces that banks had commercial reasons to denominate in it rather than, or alongside, local currency.

ABNC's involvement was routine for ambitious provincial banks of this era; the New York engraving gave notes a credibility that the issuing institution itself often could not.
