A pair of licence plates from the limousine that drove President John F Kennedy through downtown Dallas when he was assassinated on 22 November 1963 are going up for auction.
The opening bid for the plates being offered by Heritage Auctions today in Dallas is $40,000.
The plates from Kennedy's limousine were tossed in the rubbish at a Cincinnati, Ohio company that retrofitted the vehicle after the assassination.
When new plates arrived, the old plates were discarded, the auction house said.
A menu from the last dinner served to first-class passengers aboard the Titanic before it sank in 1912 will also be auctioned.
It is among a few surviving artefacts from the ill-fated ship's journey.
The pre-bidding on the menu, which featured a selection of oysters, filet mignon, roast duckling, squab and other delicacies, reached $44,000 yesterday,
Besides the menu, other Titanic relics up for sale include a recently discovered distress telegram sent by Western Union to the ship's ownership company in New York informing officials that the Titanic had struck an iceberg and was in trouble, the auction house said.
"We have struck an iceburg - sinking fast – come to our assistance," it read.
The luxury ocean liner foundered in the Atlantic Ocean on after striking an iceberg on 15 April 1912 during its maiden voyage from Southampton in England to New York. Some 1,500 people lost their lives.
Officials with White Star Line claimed in a Congressional inquiry that the company never received notice of distress from the Titanic.
Opening bid for the telegram is $20,000, the auction house said.
