The currency that replaced the Peruvian inti and has a name meaning “sun” in Spanish is the Peruvian sol.
Peru launched the sol in 1991 during a severe economic crisis. The new currency replaced the inti, which had lost much of its value during a period of hyperinflation. Choosing the name sol revived a historic Peruvian currency name while also evoking the sun, an important symbol in Andean culture.
The sol is divided into 100 céntimos and has the ISO 4217 code PEN. It was officially called the nuevo sol, or “new sol,” until 2015, when Peru changed the legal name back to sol.
This question refers to the modern currency, not Peru’s earlier sol, which circulated from the nineteenth century until 1985. The replacement date is the key distinction between the two currencies.
