5 Pesos

The Chaco 5 Pesos is one of the provincial emergency notes — locally termed "lecop" or simply bonos — issued across Argentina's interior provinces during the collapse of the convertibility system. With the federal government unable to service its obligations, at least fourteen provinces began printing their own quasi-currencies between 2001 and 2002. Chaco was among the more economically distressed, with chronic fiscal deficits predating the crisis by years.

Casa de Moneda printed these for several provincial issuers simultaneously, which creates attribution headaches — the production quality is identical across different jurisdictions, and unissued remainders complicate census data. The PS# reference remains unassigned in most major catalogs.
