Che Guevara's single strand Hair sold for 119500 USD

On October 25, 2007, the Heritage Auction Gallery of Dallas sold a strand of black hair taken from the dead body of revolutionary leader Che Guevara. The lone bidder—Bill Butler, a book dealer—paid an eye-popping $119,500 for the relic. At the time, Butler said he wanted to add a piece of this great leader to his collection of 1960s memorabilia. Earlier in the year, the same auction house had sold a lock of President Abraham Lincoln’s hair for $11,095 and one of Confederate General J. E. B. Stuart’s hair for $44,812. Hair from famous people commands high prices.

why it is happening?
For example, in Greek mythology, Mnemosyne, mother of the nine muses, stores her remarkable memory in her very long hair. In the Bible, Samson stored his strength not in his muscles but in his hair—so when his two-timing lover cut his hair, he lost his remarkable might and didn’t recover it until his hair regrew. In Japanese tradition, the sumo wrestler’s force resides in his hair; cutting a sumo’s long hair during the retirement ceremony signals the end of his fighting career. Many people have believed that the essence of a person is connected to hair, and it was a common thought that wounding hair—even if detached from the body—could cause bodily harm. By this way of thinking, West African Yoruba people protect their cut hairs lest the spirit embedded in them come under the influence of a malefactor who could exploit them. Folklore from more than a few cultures has stories of demonic sorcerers (or sorceresses) who apply love potions to captured hairs in order to facilitate an unwanted seduction. Hair has also been used in votive offerings, as when Japanese women sacrificed locks of hair to shrines for the safe return of their loved ones, or when modern Indian women donate their hair to temples in exchange of their God fulfilled their vows.
