50 Pesos

Corrientes issued its own quasi-currency during the provincial fiscal crisis of the late 1990s and early 2000s, when Argentina's federal government could no longer reliably transfer revenue-sharing funds to the provinces. These notes — formally called Letras de Cancelación de Obligaciones Provinciales, or LECOP precursors in the provincial sense — circulated alongside federal pesos as de facto legal tender within the province, accepted for tax payments and public-sector wages.

Corrientes was placed under federal intervention in late 1999, making the political circumstances around this specific issuance unusually turbulent. Notes from this period sometimes circulated well beyond their intended redemption dates simply because there was nothing else available.
