20 000 Chachos

La Rioja is one of several Argentine provinces that has periodically resorted to quasi-currency when federal transfers fall short. The province issued earlier series of "Chachos" — named after the 19th-century caudillo Ángel Vicente Peñaloza — and this 2024 iteration continues that tradition during a period of acute provincial fiscal stress. The denomination of 20,000 reflects how far inflation had compressed the practical value of earlier low-denomination issues in the series.

The QR code is a notable departure from previous Chacho emissions, allowing digital verification — an acknowledgment that trust in provincial scrip requires more than paper promises.
