10 Bolivianos overprinted on P# 192B

Bolivia's hyperinflation crisis of the mid-1980s was among the most severe in Latin American history, with annual inflation peaking above 20,000 percent in 1985. The government's response — the New Economic Policy launched under President Paz Estenssoro — stabilized the currency rapidly, but the transition left the central bank with enormous stocks of notes that were effectively worthless at face value. Rather than scrap them, the bank overprinted existing P#192B stock with sharply revalued denominations, a stopgap that bridged the old peso boliviano issues into the new boliviano framework introduced at a conversion rate of one million to one.

The overprint series is well documented but frequently found with uneven ink application, a known characteristic of the rush conditions under which the stamps were applied.
