50 Centavos Plata Boliviana

Banco Provincial de Santa-Fé operated out of Rosario, and this 50 Centavos note — payable in Plata Boliviana, the Bolivian silver peso that served as a de facto regional currency across the Río de la Plata interior — reflects how fractured Argentina's monetary geography remained well into the 1870s. Provincial banks issued their own paper, redeemable in whatever specie their region actually used, not necessarily Buenos Aires's preferred standard.

The American Bank Note Company printed both the Rosario (PS-811) and Santa Fé (PS-812) variants from what appears to be the same underlying plate, differentiated only by the place-of-issue text. A cataloger's distinction, but a commercially meaningful one at the time.
