The "Holy Grail of baseball cards," the famous 1909 Honus Wagner tobacco card once owned by hockey great Wayne Gretzky, has sold for a record-setting $2.35 million, the seller of the card said Monday. The buyer has only been identified as a Southern California collector. SCP Auctions Inc., a company that holds sports memorabilia auctions, said it bought a small share of the card. It is scheduled to be shown at a news conference at Dodger Stadium on Tuesday.
