The Queen and Duke of Edinburgh have been told that despite being antiques their re-sale value is only a few quid, probably a fiver, at a car boot sale, maybe.
The BBC TV show's experts told the Royal couple they were wasting their time, but appreciated their visit during filming at Hillsborough Castle, County Down.
Presenter Ivan Cock said "Despite Philip being one of the oldest antiques I have ever seen, he really isn't worth much; there is not much use for an elderly man who wets the bed and couldn't even boil an egg. As for his wife, lovely lady, but really - wouldn't pay over a tenner for her."
