4 Pesos de Oro

The Banco de la Provincia de Buenos Aires — founded in 1822 and distinct from any national institution — was still issuing its own currency in 1881, operating under provincial charter well after Argentina had begun consolidating its monetary framework. The provincial banks' right to issue notes would be effectively curtailed by the National Guaranteed Banks Law of 1887 and finally extinguished in 1891 following the catastrophic Baring Crisis, which brought down several Argentine financial institutions simultaneously.

American Bank Note Company produced this note at their New York facilities, a typical arrangement for Argentine provincial issuers who lacked domestic intaglio capacity and trusted ABNC's reputation for security printing. The "Pesos de Oro" denomination distinguished gold-pegged obligations from the depreciating paper pesos that plagued Argentine commerce through the 1880s — a distinction that mattered enormously to creditors.
