50 Bolivianos

Bolivia's 1985 hyperinflation — one of the worst in twentieth-century history, peaking at over 20,000 percent annually — forced a complete monetary replacement. The boliviano was reintroduced at a rate of one million old pesos per new boliviano, and this 50-boliviano note belongs to the first emission of that stabilization series, issued under Decree 21060 and the "Nueva Política Económica" shock therapy program designed by economist Jeffrey Sachs.

Printed domestically at the Casa de la Moneda in Potosí — the colonial mint now repurposed as Bolivia's national printing house — the series marked a rare instance of a country producing its own emergency redenomination notes in-house rather than contracting abroad.
