The Associated Press reports 14 strands of the U.S. president's hair sold at an auction in Texas for $6,875. The hair was supposedly cut by Jefferson's physician at the time of his death a 190 years ago.
The documentation includes a letter confirming the lock as a part of a limited number of hair samples known to exist. Other known samples belong to the Library Congress and Monticello, the home of Thomas Jefferson.
