Pre-Civil War baseball team card going on auction block in Chicago – Chicago Tribune

For decades, a circa 1860s Brooklyn Atlantics team baseball card was tucked away, first inside a secret drawer of a bedroom set and then between the pages of a photo album.

Now the pre-Civil War card that’s been in the same family for over 150 years is going on the auction block in Chicago, where it could bring as much as $50,000.

Heritage Auctions is offering it on July 30 at its Platinum Night Sports Auction held in conjunction with the 2015 National Sports Collectors Convention. Online bidding opened on Tuesday.
