The Donald P Dow collection brought top bids totaling USD 803,889, doubling expectations, said Eric Bradley, spokesman for Dallas-based Heritage Auctions.
Greg Dow said his father, who died five years ago, was fascinated with presidential assassinations.
The lock of hair, taken by Surgeon General Joseph K Barnes shortly after Lincoln was shot by John Wilkes Booth, sold for USD 25,000.
An 1861 letter written by Booth to a friend boasting about his career and value as an actor sold for USD 30,000.
"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.
