The film depicts Tom Hanks as a lone survivor stuck on a deserted island. The ball, which his character names Wilson, is depicted as his only friend.
The ball was originally made to look dirty, and spent a lot of time in the water during filming, according to Prop Store, the auction house that sold it.
Hanks was given an Oscar nomination for best actor in the Robert Zemeckis film.
The movie star lost out to Russell Crowe for his role in the film Gladiator.
During the film, Hanks talks to Wilson as a way to keep his sanity while struggling to survive.
