A Dallas auction of Abraham Lincoln memorabilia made over $800,000 on the collection, which included a lock of the former president’s hair. The seller, Greg Dow, said the extensive collection belonged to his father, who was fascinated with presidential assassinations.

The Donald P. Dow collection, as it has been called, doubled expectations of the Dallas-based company who conducted the sale. The full price of the bids totaled $803,889, said Eric Bradley, spokesperson for Heritage Auctions.

Some of the most notable items at the auction aside from the famous follicles included an 1861 letter written by Lincoln’s assassin John Wilkes Booth, which sold for $30,000. Don Ackerman, Consignment Director for Historical Americana at Heritage Auctions, called the letter “exceedingly rare and valuable” because most documents linked to Booth were destroyed shortly after Lincoln’s death. “The Dow Collection gave us a unique perspective of the assassination and I doubt we’ll ever see a grouping like this outside of a museum setting,” said Ackerman.

Other items from the Dow collection strayed a little more to the gory side. These included a scrap of bloodstained linen from Lincoln’s deathbed which sold for $6,000, and a set of oil paintings created for a carnival sideshow, which supposedly depicted Booth’s mummified remains. The set of four paintings sold for $30,000.

The lock of hair was taken from the president’s head by Surgeon General Joseph K. Barnes shortly after Lincoln was shot by Booth on April 14, 1865. Lincoln remained in a coma for nine hours before dying on the morning of the next day.

Donald P. Dow died five years ago, leaving his unique collection to his son. “It’s time to let somebody else have fun owning it,” said Greg Dow.
