50 Pesos

This note is a product of the 2001–2002 Argentine financial collapse — specifically the provincial quasi-currency emergency that followed the freezing of bank deposits known as the "corralito." When the federal government suspended convertibility and access to accounts, several Argentine provinces resorted to issuing their own paper instruments to pay salaries and keep local economies liquid. Buenos Aires Province was among the largest issuers, and these patacones, as they were popularly called, were accepted by major supermarkets and even some utility companies under informal federal pressure.

Pereira signed as Tesorero; Zufriátegui as Contador General. By mid-2002 the province had issued several denominations, with the 50-peso patacón among the higher face values in the series.
