The tooth fairy never brought us this kind of loot when we were little kids, but then again, the undeniably brilliant voice of one of the most beloved singers of all time never brushed past our pearly whites. One of John Lennon's teeth is going under the hammer Nov. 5 in Stockport, England, and is expected to fetch almost $16,000 -- and perhaps much more -- during Omega Auction's Vinyl, Music & Film Memorabilia sale.

The tooth was gifted by the the late Beatles star to his then housekeeper Dot Jarlett when she was working for him at his Kenwood mansion in Surrey, England, in the late '60s.

"He was in the kitchen and he had this tooth which he had wrapped in a piece of paper," Dot's son, Barry Jarlett, told the BBC. "He said, 'Dot will you dispose of this' and then he said, 'Or, as your daughter's a Beatles fan, you can give to her as a souvenir.'"

"It is something that we felt was very personal and my mum actually gave it to my sister who has kept it safe," Jarlett continued. "He was very generous to my mother."

Omega Auctions's Karen Fairweather says the Lennon tooth, which comes with an affidavit verifying its authenticity signed by Dot Jarlett, is truly one-of-a-kind. "This is the most wonderful and weird item that we have ever had for sale," says Fairweather. "It is a truly unique item and it is really difficult to put a value on it ... it is not unknown for these items as rare as this to reach six figures."
