If you don't mind me asking, how did you come across such a card?
Over 10 years ago, my aunt was living in Cincinnati. Her husband at the time (ex now) was walking through some place that had held a baseball card show the day before. He found the Berra and a couple other cards lying on the ground. He let the venue know that he had found them, in case someone, realizing that they'd lost the card, called looking for it. Nobody ever called, so the venue told him he could keep it. A couple months back I had my first child, a son, and my aunt thought that I might like to have it, to sell or to give it to him someday, she didn't care. That's the story.
