The oldest existing version of the FA Cup, presented to winning teams between 1896 and 1910, is due to be sold at an auction in London.
It is thought the 110-year-old trophy could become the world's most expensive item of football memorabilia.
The solid silver trophy was a replacement for the first ever cup, stolen from a shop window after Aston Villa won it a second time.
Auctioneers Christie's believe it could fetch as much as £300,000.
The trophy, the only FA Cup to come up for sale, is part of a memorabilia auction that also includes Alan Ball's 1966 World Cup winners' medal.
It ceased to be used by the Football Association after the body realised it did not own the copyright when the holders
Manchester United made a replica.
The obsolete cup was then given to Lord Kinnaird to mark his presidency of the FA for more than two decades.
It is likely to be the oldest still existence as the stolen original was likely to have been melted down.
