They have also shelled out for some French toast left on Justin Timberlake’s breakfast plate, a drop of Ronald Reagan’s blood and even a tissue used by Scarlett Johansen.
But though some of these may sound gross, they are merely the bottom end of a booming multi million pound market for celebrity memorabilia, said the report by auction analysts.
At the other end of the scale, rich collectors are spending £1 million or more on the dress Judy Garland wore in the Wizard of Oz or nearly three times as much on James Bond’s Aston Martin DB5.
A report by Barnebys, which lists a million items from 2,000 auction houses worldwide, said a ‘significant’ number of its lots are now celebrity memorabilia, but not all are glamorous.
Among those it has seen sold are William Shatner’s kidney stone – which he sold for £14,000 to raise money for charity – a lock of Justin Bieber’s hair and John Lennon’s tooth.
Its report said: “The cult of celebrity is so powerful it seems that collectors will pay more for memorabilia touched and used by famous people.
“They believe it has something of the essence of the celebrity who once owned it and in this way that get to own a piece of the celebrity.”
Outfits are particularly big business, from the cowardly lion’s costumer in the Wizard of Oz, which sold for £2.3 million, to an evening gown Audrey Hepburn wore in Breakfast at Tiffany’s which sold for around £470,000.
But almost any famous prop will sell, say auctioneers. A whip used by Harrison Ford in the role of Indiana Jones went for £47,000 and a Delorean in Back to the Future sold for £417,000 for instance.
At the less glamorous end of the scale, a tissue used by Scarlett Johansen was sold on eBay for £3,600.
