The tooth fairy's trash became another man's treasure Saturday when a discolored molar that once belonged to John Lennon was put up for auction. 

The winning bid came in at 19,500 pounds (U.S. $31,200), according to auction results posted online. 

Michael Zuk, a Canadian dentist, is claiming responsibility for the winning bid. Omega Auction House, which sold the tooth, did not immediately respond to requests for comment Saturday. 

Lennon gave the tooth to Dorothy "Dot" Jarlett when she worked as his housekeeper at his Kenwood home in Weybridge, Surrey, according to her son, Barry. Jarlett, who was employed between 1964 and 1968, developed a warm relationship with Lennon, her son said. 

"She was very close with John, and one day whilst chatting in the kitchen, John gave my mother the tooth (he had been to the dentist to have it removed that day) and suggested giving it to my sister as a souvenir, as she was a huge Beatles fan," he said. "It has been in the family ever since." 

With the exception of the past two years, the tooth has been in Canada for 40 years after Dot Jarlett's daughter married a Canadian. 

Barry Jarlett, who said his mother is now 90 years old, said it was the right time to pass it on rather than to risk the tooth getting lost. 

Karen Fairweather, the owner of Omega Auction House, told CNN last month that the tooth is too fragile for DNA testing but she has no doubt about its authenticity. 
How old is she?
