100 000 Australes

The 100,000 Australes note is the clearest artifact of Argentina's hyperinflationary collapse under the Austral currency system. Introduced in 1985 as a stabilization measure — with one Austral replacing 1,000 Pesos Argentinos — the Austral itself disintegrated within six years. By 1991, inflation had exceeded 3,000% annually at its worst, forcing denominations that would have seemed absurd at launch.

The Austral was replaced by the Peso Convertible in January 1992 at a rate of 10,000 Australes to one Peso, rendering this note worth one cent. P#337 sits at the very top of the denomination ladder — no higher Austral value was ever issued.
