Banco de la Provincia de Buenos Aires was one of the most powerful provincial institutions in Argentina's fragmented pre-unification banking period, and by 1869 it was operating under the revised provincial charter that gave it near-monopoly note-issuing authority within Buenos Aires province. The American Bank Note Company in New York handled the printing — a common arrangement for Latin American issuers seeking security printing that domestic facilities could not yet reliably provide.

The PS# prefix in the Pick catalogue places this firmly in the specialized South American provincial issues section. Surviving examples from this 1869 series tend to show heavy circulation wear, consistent with a period when Buenos Aires commerce was expanding rapidly and lower-denomination paper moved briskly through trade.
