The Antiques Roadshow is famous for valuing interesting items, usually antiques. Joanne Fiske from Gorleston-on-Sea in Norfolk won a hat worn by Michael in a newspaper competition back in 1991.
Mrs Fiske visited the Antiques Roadshow last week when it was filmed at Somerleyton Hall in Suffolk and took the hat along to be valued. Experts at the programme told her that it could be worth a staggering £25,000.
The programme will be shown on the BBC1 next spring.
