8 Pesos Fuertes

The Banco de Londres y Río de La Plata was a British-backed institution established in Buenos Aires in 1862, one of the first foreign commercial banks to operate in Argentina. The Rosario branch opened shortly after, serving the booming grain and cattle export trade along the Paraná river corridor. This 8-peso-fuertes denomination is an unusual one — not a standard unit of commercial accounting — and likely reflects the bank's attempt to service specific exchange values tied to gold conversion rates current at the time of issue.

The American Bank Note Company printed for dozens of South American issuers during the 1860s, and the firm's New York production gave these notes a security quality that locally printed alternatives could not match.
