1 Peso

Catamarca's 2001 emergency peso was one of dozens of provincial quasi-currencies — generically called "patacones" or "lecops" depending on the issuer — that flooded Argentina when the federal government's convertibility regime began collapsing and provinces lost access to central bank financing. Catamarca, one of the poorest provinces in the northwest, issued these notes to pay salaries and suppliers when hard currency simply wasn't available.

Provincial issuances varied wildly in how seriously markets treated them. Catamarca's notes traded at discounts to face value almost immediately.
