5 Pesos

Entre Ríos was one of several Argentine provinces that issued its own quasi-currency during the 2001–2002 convertibility crisis, when the federal government froze bank deposits and the national peso effectively ceased to function as a medium of exchange. These provincial notes — technically "bonds" or "letras de cancelación de obligaciones" — circulated as de facto money, accepted by local businesses and government offices out of necessity rather than legal obligation.

Casa de Moneda's Paraná facility handled production, keeping the physical manufacturing within the province. The PS# designation reflects its status as a subnational emergency issue, not a standard central bank note.
