10 Australes

La Rioja's austral notes were issued under provincial emergency powers at a moment when Argentina's national monetary system was already buckling. The austral itself had only been introduced federally in June 1985 as part of the Alfonsín government's Austral Plan — a shock stabilization attempt — so a province printing its own denominated paper within the same unit barely a year later signals how quickly that plan was losing credibility at the regional level.

Casa de Moneda printed the note, meaning this is one of the few quasi-fiscal provincial emissions with the imprimatur of the national mint behind it — an awkward arrangement that reflects the fiscal desperation of underfunded interior provinces rather than any formal monetary authorization.
