A LEATHER bomber jacket that belonged to slain US president John F. Kennedy has been sold at auction for $US665,500 ($646,000), far exceeding the initial estimate.
The brown Air Force One jacket was one of 700 lots put on the auction block on Sunday after the family of David Powers, a special assistant to Kennedy, discovered a treasure trove of JFK memorabilia in the Powers family home.
The jacket was initially estimated at $US20,000 to $US40,000.
Among the other JFK items up for sale, nearly 50 years after his assassination, were photographs, campaign posters, letters and books belonging to the president.
The John McInnis auction house in Massachusetts said on its Facebook page that the jacket was sold for $US570,000. With the premium, the total was $US665,500. The sale lasted more than six hours, the house said.
