Bonhams will auction the second medal thrown into the crowds by José Mourinho at the end of the 2005-6 Premier League Season.
The medal will appear at its sale of Sporting and Golf Memorabilia at Chester on 24th February 2010.
The Portuguese former Chelsea manager was presented with the second medal minutes after he had thrown his first winner's medal, along with his blazer, to the delighted spectators at Stamford Bridge.
Mourinho said at the time: "The medal was for everybody but I think the person in the crowd who got the medal is a lucky guy who goes home with a fantastic memory.
"Or goes to eBay and makes a fortune," he added.
In 2008, Bonhams marked Mourinho's words, selling the first medal for £21,600 on behalf of a Chelsea fan.
The second medal has attracted a pre-sale estimate of £12,000-15,000.
