Beatles fans often clamor to get their hands on just about anything related to the Fab Four, but this is one piece of memorabilia that may give pause to even the most rabid collector: a tooth, purportedly pulled from the mouth of John Lennon.

Set for auction next month, the cavity-marred molar was given to Dorothy “Dot” Jarlett when she worked as Lennon’s housekeeper. Her son Barry explains, “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. It has been in the family ever since.”

Karen Fairweather, the owner of Omega Auction house, says that while some potential buyers have expressed interest, others think it’s gross. “We get a lot of people buying memorabilia as investments,” she said. “Or it could just be a fan that really, really wants a part of John Lennon.”

The tooth will go up for auction on November 5 with a reserve bidding price of just under $16,000.
