Even if you're not a baseball fan, you've probably heard of the Honus Wagner "cigarette" card.

One of the rarest trading items ever produced, the 1909 "cigarette" card even has its own plaque in the Baseball Hall of Fame, where it's deemed sports' "most famous collectible."

There are less than 60 of these cards in existence, and it has become quite a spectacle whenever they go on sale. Five years ago one of the cards sold for a record $2.8 million, and now another card that's on the block could go for more.

According to the New York Post, a Wagner card currently on display at Audemars Piguet Flagship Boutique on East 57th Street could fetch as much as $3 million.

“If you collect art, you dream to own an original Picasso ... if you collect fine cars, you would dream to one day own a 1957 Ferrari 250 Testarossa," Goldin Auctions said in the card's description. "In the world of sports memorabilia, it is the ... Wagner, and this is the finest example you will likely have the chance to own in your lifetime."

The starting bid for the card was $500,000, and the auction ends on April 5.
