D.B. Cooper bills sold at auction

Fifteen tattered $20 bills recovered from the 1971 D.B. Cooper skyjacking sold for more than 120 times their face value at a Dallas auction.

Heritage Auction Galleries said the bills sold for a total of more than $37,000 -- two to three times higher than expected.

Winning bidders paid about $6,500 each for two of the $20 bills. The money has the handwritten initials of investigators who examined the bills, which were found buried in sand in 1980.

Cooper skyjacked a flight from Portland, Ore., to Seattle, claiming he had a bomb.
