The Banco y Casa de Moneda de la Provincia de Buenos Ayres occupied an unusual institutional position — it combined commercial banking functions with the provincial mint, an arrangement that gave Buenos Aires extraordinary monetary autonomy from the Argentine Confederation throughout the mid-nineteenth century. This note dates from the period following the 1862 national unification, when the province was still operating its own currency infrastructure largely independent of federal control, a source of persistent tension with the nascent national government in the same city.

The PS prefix in the Pick reference signals a privately-issued provincial instrument, not a national emission.
