The Banco de Buenos Ayres was established in 1822 as Argentina's first formal bank of issue, and its notes circulated during one of the most volatile monetary periods in the region's early republican history. The bank's charter was effectively undone by the financial pressures of the Cisplatine War against Brazil, which drained specie reserves and forced suspension of convertibility in 1826 — a suspension that proved permanent. Notes issued through 1827–1829 were already inconvertible by the time they left the teller's window.

PS#335 at this denomination represents the upper tier of the bank's issue range, where survival rates are predictably thin. The bank itself was absorbed into the Banco de la Provincia de Buenos Aires in 1836.
