1/2 Real Plata Boliviana

Banco del Rosario was one of several provincial banks chartered in Argentina during the brief liberal banking experiment of the 1860s, before the national government moved to consolidate currency control. The Santa Fé institutions were notoriously short-lived — most collapsed or were absorbed within a decade, and their lower-denomination fractional notes saw the heaviest circulation and the highest attrition rates.

The Real Plata Boliviana was a colonial monetary unit still in everyday use across the Río de la Plata region long after independence, particularly for small transactions where the new national denominations had failed to penetrate.
