100 Pesos Convertibles de Curso Legal 1st issue

This note is a product of the Convertibility Plan, which pegged the Argentine peso 1:1 to the US dollar from April 1991 — a monetary straitjacket that initially crushed hyperinflation but eventually collapsed in the crisis of 2001-2002. The "Convertibles de Curso Legal" wording was legally mandated by the Convertibility Law itself, requiring all currency to declare its dollar-backed status on the face of the note.

The two series A signature varieties are distinguished solely by the rosette pattern at right — fine or coarse — a detail that matters to specialists but was never officially announced as a deliberate variant. Casa de Moneda's quality control during this period was inconsistent enough that such differences occasionally crept through unplanned.
