The Banco de la Provincia de Buenos Aires was not the national central bank — it was a provincial institution, and in 1881 that distinction carried real political weight. Argentina's national banking law of that year began consolidating monetary authority in Buenos Aires, and provincial banks found themselves increasingly squeezed. This note was issued right at that inflection point, before the province lost its note-issuing independence entirely in the crises that followed through the late 1880s.

ABNC's engraving work for Argentine provincial banks during this period is consistently fine, produced from steel-engraved plates at their Manhattan facilities. The PS# prefix in the Pick catalogue denotes its classification as a South American provincial issue, separate from the national series.
