The Confederación Argentina operated as a rival state to the Buenos Aires Province government between 1853 and 1862, following Buenos Aires's refusal to ratify the new federal constitution. These notes were issued under that contested federal authority — the "Gobierno Nacional" designation was politically charged, not merely administrative. Buenos Aires rejected its legitimacy outright and ran its own parallel financial system throughout the period.

PS# prefix places this in the Specialized catalog under semi-governmental or provisional issuers. Surviving examples from the 1857 Confederación series are genuinely scarce; the interior provinces that formed the Confederación had thin commercial networks and limited note circulation relative to the port economy centered on Buenos Aires.
