50 Intis

The Inti was introduced in February 1985 as Peru replaced the Sol at a rate of 1,000 to one — an attempt to reset public confidence during a period of severe fiscal deterioration. The denomination held reasonably well through 1986, but by 1987 inflation was accelerating sharply toward what would become hyperinflation by 1988–1990, ultimately requiring another redenomination into the Inti Millones.

Two printers supplied this series: Casa da Moeda do Brasil and De La Rue in London. Dual sourcing of the same denomination across two continents was a practical hedge against supply disruption, though it occasionally produced subtle variation in ink saturation between print runs.
