1000 Australes

Argentina's hyperinflationary spiral of 1989 — the same crisis that pushed annual inflation past 3,000% and forced Raúl Alfonsín to hand power to Menem five months early — drove several provinces to issue their own emergency quasi-currency. Salta's australes notes were essentially provincial bonds forced into circulation as wage and payment instruments when the federal government could no longer guarantee liquidity to the interior.

Casa de Moneda printed these under extraordinary pressure; the federal mint was simultaneously handling multiple provincial emergency issues that year. The watermark is the sole security feature — modest by any measure, but enough to deter crude counterfeiting in a province far from the capital.
