1 Real = 12 1/2 Centavos Fuertes

The Banco de Corrientes was a provincial institution operating at a time when Argentina's banking system was genuinely fractured — each province could charter its own bank and emit its own paper, with wildly uneven results. The fractional denomination here, one real equated to twelve and a half centavos fuertes, reflects the painful arithmetic of currency transition: the old colonial real system being formally converted into the decimal peso fuerte, but not yet abandoned in everyday commerce.

Corrientes province had a particularly turbulent monetary history in this period, still recovering economically from the devastation of the War of the Triple Alliance, which ended in 1870.
