5 Pesos

Argentina's provincial quasi-currencies of the early 2000s are collectively called "patacones" in casual usage, but that term strictly belongs to Buenos Aires province. Catamarca's issues were formally styled "Letras de Cancelación de Deudas" — debt-cancellation instruments, not banknotes in any traditional sense. They emerged from the fiscal stranglehold of the 2001 convertibility crisis, when provinces lacked sufficient pesos to pay public employees and suppliers and turned to scrip as a stopgap.

Catamarca was among the smaller and more economically dependent provinces, and its issues circulated in a narrow local economy. Redemption was uneven across the series.
