The monetary unit of Peru between 1985 and 1991. It was divided into 100 centimos. It replaced the sol, but was overtaken by hyperinflation, and was replaced by a new sol in 1991.

I think inti is the Quechua (Inca) word for 'sun', Spanish sol.

The symbol was I/. as in I/. 5.00. Postage stamps in 1991 were denominated in millions of inti, as e.g. I/m 0.25.

Inti was the Incan Sun god as well as the god of rainbows. He was thought to be the son of their Creator Viracocha and Viracocha's wife Mama Quilla, goddess of the Moon. He was also thought to be the father of the first Inca, Manco Capac and Mama Oello.

Inti was represented as a golden disc with a human face. He was also known as Apu Punchau, which means "head of the day". The ruling Inca was considered to be the living representative of Inti.
