NEW YORK (AP) — It's worth a lot more than your old baseball cards. A card from the 1860s is going up for auction in a month. The pre-Civil War Brooklyn Atlantics team card has been in the same family for over 150 years. The seller is Florence Sasso, of Great Barrington, Massachusetts. Her great-great-uncle, Archibald McMahon, was an outfielder for the squad. He's pictured in the photo with eight teammates. Heritage Auctions estimates it could go for $50,000.
