5 Pesos

The Chaco peso emerged from Argentina's 2001–2002 financial collapse, when the federal government froze bank deposits under the corralito and provincial governments — starved of federal transfers — began printing their own quasi-currencies to pay salaries and keep local commerce moving. Chaco was among more than a dozen provinces that issued these bonos; the notes circulated alongside the national peso at par, by provincial decree, and were accepted under varying degrees of public reluctance.

Casa de Moneda printed them in Buenos Aires under contract, which gave the series more physical credibility than some provincial issues run off by regional printers. Redemption followed the 2002 federal bailout agreement, which absorbed most provincial debt and removed these notes from circulation within a few years.
