20 Pesos Bolivianos

Banco Oxandaburu y Garbino was a private commercial bank operating out of Potosí during Bolivia's brief experiment with free banking in the late 1860s. The period produced a handful of short-lived issuing institutions, most of which collapsed or were absorbed within a decade as the Bolivian state moved to consolidate monetary authority. This note is among the rarer survivors of that episode.

The "Pesos Bolivianos" denomination places it firmly before the 1963 monetary reform — but more immediately, before the 1870s fiscal pressures that killed off most of the private banks in the Potosí region entirely.
