1 Peso La Provincia de Buenos Ayres

The Banco de la Provincia de Buenos Aires was the oldest and most powerful provincial bank in Argentina, and by the 1870s it operated with a degree of autonomy that the national government in Buenos Aires city found increasingly inconvenient. This note circulated during the years when the provincial peso and the national peso coexisted uneasily — a monetary tension that would not be resolved until the federalization of Buenos Aires in 1880 effectively stripped the province of its capital and forced a reckoning with its currency.

ABNC's involvement was typical for South American issuers of the period seeking engraving quality unavailable domestically. The S481 designation places this within the Pick specialized catalog for Latin American provincials rather than the main Argentine sequence.
