20 Pesos

Argentine provinces began issuing their own quasi-currencies — known as cuasimonedas — during the severe liquidity crisis of 2001–2002, when the federal government effectively ran out of pesos to transfer to the provinces. Tucumán's emission was part of that wave, used to pay provincial employees and contractors when hard currency simply wasn't available. Unlike the larger provinces, Tucumán's series remained relatively modest in total volume.

The PS prefix in the Pick reference places this firmly in the emergency provincial issues, a category that became obsolete almost as quickly as it appeared — most cuasimonedas were recalled and redeemed at par by 2003–2004 as the national economy stabilized under Kirchner.
