The dual denomination — 20 Bolivianos on one face, 2 Bolivares on the other — reflects Bolivia's transitional monetary period of the mid-1940s, when the country was shifting its unit of account from the Boliviano to the Bolivar. The Bolivar was introduced at a ratio of 1 Bolivar to 10 Bolivianos, making this a bridging note designed to function during the crossover rather than as a permanent issue.
