A dental mould of Elvis Presley's mouth is expected to fetch a jaw-dropping $16,000 (£10,000) when it hits the auction block.
Dentist Henry J. Weiss kept the plaster model, which includes an extra crown, in case the Jailhouse Rock star ever chipped one of his teeth, and even referred to it as "the King's Crown".
Bosses at Omega Auctions believe the bizarre souvenir will be a big hit with fans and pull in as much as $16,000 when it goes under the hammer.
A spokesperson says, "It is the only one in existence and we expect there to be considerable interest."
The mould will come with letters of authenticity from the singer's road manager when it is sold in Stockport, England on 25 February (12).
