50 000 Chachos

La Rioja's "Chachos" are provincial quasi-currency — bonos issued by the Rioja provincial government to cover salary and supplier payments when federal transfers fall short. The name references Chacho Peñaloza, the 19th-century caudillo from the province, a choice that is equal parts regional pride and deliberate political signaling. This 50,000-denomination note belongs to a reissued series that emerged amid Argentina's broader fiscal crisis of the early 2020s, as several provinces revived the bono mechanism that had last seen widespread use during the 2001–2002 collapse.

The QR code is functional rather than decorative — it links to a provincial verification system, a concession to the fact that counterfeit provincial scrip has been a documented problem in past Argentine bono cycles.
