4 Reales Plata Boliviana

The Banco Provincial de Santa Fé was established in 1874 as a provincial institution operating under Argentine law that permitted individual provinces to charter their own banks of issue — a federalist arrangement that produced a patchwork of competing currencies across the republic before the Banco Nacional ultimately consolidated control. This note denominated in Reales Plata Boliviana is a direct artifact of that transitional monetary environment, where Bolivian silver coinage still functioned as a practical unit of account in the Litoral region despite Buenos Aires's own peso reckoning.

The Rosario branch distinction matters: PS-807 shares the same basic issue but specifies Santa Fé as the place of payment, making branch identification on surviving examples the key to correct cataloguing.
