4 Reales Bolivianos

Banco Domingo Garbino was one of Bolivia's earliest private banking ventures, operating in an era when the national government had yet to establish any central monetary authority. The 4 Reales denomination is notable because it straddles two monetary systems — the real was already being displaced by the boliviano at this point, and notes denominated in reales were becoming anachronistic almost as soon as they were issued.

PS#1801 designation places this firmly in the Andean private bank series documented by Pick's specialized catalog. Survival rate is extremely low; Bolivian private bank paper from this decade is among the scarcest in South American notaphily, largely because most institutions failed before redemption infrastructure was ever established.
