STEVE INSKEEP, HOST: Good morning. I'm Steve Inskeep. This could happen to anybody. You want to play a chess game, but one of the rooks is missing. Happened centuries ago, apparently. Five chess pieces vanished in Europe. The remaining pieces are the Lewis chessmen, carved in walrus ivory in the 1100s. Most are artifacts in the British Museum. Now one of the missing pieces turned up on a Scottish island. A man bought it decades ago for 5 British pounds, and now it may be worth 1 million.
The artifact was carved from walrus ivory during the 12th century and comes from the Viking era. It's estimated that the piece is worth more than a million dollars.
