10 Pesos

Entre Ríos was one of several Argentine provinces that issued emergency quasi-currency during the 2001–2002 convertibility collapse, when the federal government froze bank accounts and the peso's peg to the dollar disintegrated. These provincial bonds — called *patacones* in Buenos Aires, *lecops* federally, and *federales* in Entre Ríos — circulated as de facto legal tender for wages, taxes, and retail purchases because there was simply no alternative.

Casa de Moneda printed these under contract, which gave them a degree of physical credibility the public found reassuring. Most provincials redeemed their scrip by 2003–2004 as federal transfers resumed, and surviving circulated examples typically show heavy handling from genuine day-to-day use.
