4 Reales Plata Boliviana

Banco del Comercio was one of several provincial Argentine free-banking era institutions that issued notes denominated in Bolivian silver reales rather than the national peso — a reflection of how thoroughly Bolivian coinage had penetrated the Río de la Plata interior during the mid-nineteenth century. In Entre Ríos province, where Gualeguay sits, Bolivian fractional silver circulated more reliably than domestic coin throughout the 1860s.

Argentine provincial bank notes from this period are genuinely rare survivors. Most free-banking institutions operating outside Buenos Aires were short-lived, and redemption or simple destruction claimed the bulk of their paper. The PS prefix in the Pick numbering signals exactly that — South American private and provincial issues where census populations remain poorly documented.
