50 Pesos Fuertes

The Banco de Londres y Río de la Plata was the first joint-stock bank to operate in Argentina, established in Buenos Aires in 1862 as a British-backed institution and quickly expanding to Rosario, then the commercial hub of the booming Litoral grain economy. This Rosario branch issued its own notes — separately cataloged from the Buenos Aires series — reflecting the provincial banking freedoms that still operated before Argentina's later centralization efforts eliminated private note issue.

ABNC's work for South American clients in the 1860s typically involved deeply engraved plates shipped from New York, with local overprinting or branch designation added afterward. The "Pesos Fuertes" denomination — hard pesos, tied nominally to silver — was the standard commercial unit in the Río de la Plata region before the peso moneda nacional replaced it in 1881.

PS#1740 is among the scarcer Rosario branch denominations to survive in any form.
