The Junta de la Administración de la Casa de Moneda was the monetary arm of Buenos Aires province, not a national institution — Argentina had no unified central bank at this point, and each province managed its own paper emissions. This note predates the Confederation's first serious attempt at monetary consolidation by over a decade.

Buenos Aires printed its own currency locally throughout this period, which distinguishes it from contemporaries like the Banco Nacional notes that relied on foreign presses. PS#386 sits in a series that circulated during the Rosas era, when the province's finances were chronically strained by military expenditure and trade disruptions linked to the Anglo-French blockade of the Río de la Plata, which began in 1845 — the year after this note was issued.
