T206 Honus Wagner
From BR Bullpen
The 1909 T206 Honus Wagner is considered the most valuable baseball card in the world. The card sold at an eBay auction for a record $1.265 Million.
Although an estimated 50 to 200 were distributed to the public originally, few have survived to the present day. The T206 set is the most sought after set of prewar baseball cards, and this, as well as Wagner's greatness, are the cause of the card's extremely high value.
Wayne Gretzky and Todd McFarlane have both owned examples of this card.
