50 Pesos Plata Boliviana

The Banco Provincial de Santa Fé was one of the provincial banks operating under Argentina's decentralized banking regime of the 1870s, before the Banco Nacional and eventually the Banca Nacional Mortgage system consolidated provincial note-issuing authority. This Rosario issue and the Santa Fé variant (PS-818A) are the same printed plate, differentiated only by the place of issue text — a common ABNC practice when a client bank operated branches across more than one city.

The denomination in pesos plata boliviana reflects the transitional currency accounting still common in the Río de la Plata region during this period, when Bolivian silver pesos remained a practical unit of account alongside Argentine paper emissions.
