5 000 000 Pesos Bolivianos

Bolivia's hyperinflation of 1984–1985 was among the worst in recorded history, with annual inflation peaking at roughly 23,000 percent. Notes like this one were a direct consequence — the 5,000,000 peso boliviano denomination was not a product of monetary ambition but of arithmetic desperation. The boliviano was introduced in September 1985 at a conversion rate of one million pesos bolivianos to one new boliviano, instantly rendering the entire peso series obsolete.

Printing was handled by Argentina's Casa de Moneda in Buenos Aires, a common regional arrangement when a central bank's domestic facilities couldn't keep pace with demand — which Bolivia's emphatically could not.
