10 Pesos

Mendoza's provincial quasi-currency program was a direct consequence of Argentina's 2001–2002 financial collapse, when frozen bank deposits and a federal cash shortage forced most provinces to issue their own emergency scrip. Mendoza's series, known locally as "Petros," circulated alongside federal pesos and was accepted by provincial employers and merchants under agreements that the national government grudgingly tolerated. By 2007, most provinces had wound down their parallel currencies — the fact that Mendoza was still printing at this date suggests either a delayed redemption schedule or continued regional liquidity pressure well after the acute crisis had passed.
