50 Pesos

Provincia de Jujuy is one of several Argentine provinces that issued its own quasi-currency during and after the 2001–2002 peso convertibility crisis, when the federal government froze bank accounts and a catastrophic shortage of circulating cash forced provincial administrations to print their own emergency money. These provincial notes — generically called "cuasimonedas" — functioned as wage payments, circulated alongside federal currency, and were eventually redeemed at par under a 2003 national agreement.

The 2007 date places this note in the tail end of that redemption window, well after most other provinces had wound down their parallel issues. Why Jujuy was still printing at that date is the relevant question here.
