1 Real Plata Boliviana

Banco del Rosario de Santa Fé was one of the provincial banks that proliferated across Argentina in the 1860s under a loose free-banking framework, before the national government moved to consolidate monetary authority in the 1870s and 1880s. The denomination in reales plata boliviana is telling — Bolivia's silver coinage circulated heavily in the interior provinces and was often more trusted than domestically minted currency, so tying a note's face value to that standard was a commercial decision as much as a monetary one.

Printed locally in Rosario rather than sent abroad to the established security printers of London or Paris, which was the more common route for prestige issues.
