1 Peso Plata Boliviana

Banco del Litoral was a short-lived Argentine private bank operating out of Buenos Aires during the brief window of provincial free banking that preceded the tighter regulatory frameworks of the 1880s. The "Plata Boliviana" denomination is the telling detail here — it pegged the note's value explicitly to Bolivian silver coinage rather than Argentine metallic standards, reflecting the monetary fragmentation of the Río de la Plata region where multiple silver currencies circulated simultaneously and public trust required an anchor the issuing bank itself could not provide.

PS numbering places this firmly in the Standard Catalog's private South American issues — scarce in any grade, rarely seen outside major specialist auctions.
