10 Pesos

Argentina's provinces began issuing quasi-currency — known as "lecops" or, more specifically by province, under various local names — as the national economy collapsed in 2001. Catamarca's emission was authorized under provincial emergency legislation as federal transfers dried up and the provincial government needed to pay wages and suppliers. These notes circulated alongside, and often instead of, federal pesos in local commerce.

The national government eventually absorbed and cancelled most provincial paper through a 2002–2003 redemption program. Catamarca's issues were among the smaller-volume emissions, making surviving circulated examples harder to locate than the more heavily printed Patacones of Buenos Aires province.
