"Pele is like the Marilyn Monroe of the sports world. He is such an icon and a great ambassador for football," Martin Nolan, executive director of Beverly Hills-based Julien's Auctions, told Reuters.
The three-day auction will take place in London from June 7-9 and will be preceded by a public exhibition starting June 1.
Pele, whose given name is Edson Arantes do Nascimento, became in 1958 at age 17 the youngest ever person to play in, and score in a World Cup final. He went on to help Brazil to World Cup victories in 1962 and 1970, and holds the Guinness World Record for most goals in a career with 1,283.
Now 75 years old, and after recent replacement hip and prostate surgery, Pele said that having donated much of his collection to the city of Santos, he had "decided to allow fans and collectors to own a piece of my history as well. I hope they treasure these artefacts and share my story with their children and generations to come."
He said a portion of the proceeds will be donated to the Pequeno Principle children's hospital in the Brazilian city of Curitiba.
The top item for auction is a Jules Rimet trophy that was created especially for Pele by world football body FIA and the Mexican government after he led Brazil to the nation's third World Cup victory in Mexico in 1970. It is inscribed with his three wins for Brazil.
Julien's has placed an estimated price of $400,000 - $600,000 on the trophy but says it could sell for much more.
"It is such a unique item. We think that is a very conservative estimate. This is possibly something that could sell for up to one million dollars," said Nolan.
Peel's three World Cup medals are expected to fetch up to $200,000 (£140,700), while the ball with which he scored his 1,000th goal is expected to sell for $40,000-$60,000. The player's 1977 New York Cosmos NASAL championship ring, 2004 Summer Olympics Torch Relay and L'Equipe Athlete of the Century award are also for sale.
Yet the most humble and precious item of all, if it can be verified, may be a makeshift football ball made of rolled-up socks that the pre-teen Pele kicked around the streets of Nauru.
"We have softball stitched up in canvas but we haven't definitively established yet that we have that first ball. If that ball was to exist it would be phenomenal," said Nolan.
