½ Real Plata Boliviana

Banco Argentino operated out of Paraná, capital of Entre Ríos province, during the brief and chaotic window when Argentine provincial banking was still largely unregulated. The denomination itself — half a Bolivian silver real — reflects the monetary confusion of the period: Bolivia's silver reales circulated widely in the Littoral provinces, and issuers denominated fractional notes in whatever unit the local market would accept.

ABNC handled the printing, as they did for most South American provincial banks of the 1870s. The note is among the scarcer PS-prefixed Argentine issues, likely because Banco Argentino's operational life was short and redemption records incomplete.
