1000 Intis

The Inti was introduced in 1985 to replace the Sol at a rate of 1,000 to 1, itself a response to inflation that had been accelerating since the late 1970s. By the time this 1,000-denomination note entered circulation, the currency was already under severe pressure — within two years of the series ending in 1988, Peru had abandoned the Inti entirely, replacing it with the Inti Millones and then, in 1991, the Nuevo Sol.

Thomas De La Rue printed the series under what were, by then, fairly routine contract terms with Latin American central banks. The watermark is the primary security measure — modest for a high-denomination note circulating during hyperinflationary conditions that would ultimately peak above 7,000% annually.
