auction (拍卖). She put a $10 price tag on it, deciding against $15 because it would have cost her an extra 20 cents. Later that night she got a few odd inquiries-someone wanting to know whether the card was real, someone wanting her to end the auction and sell him the card immediately. The card is actually 139 years old. Sports card collectors call the find "extremely rare" and estimate the card could fetch five, or perhaps, six figures at auction. Just like that, Bernice is the least likely character ever for a rare-baseball card story. "I didn't even know baseball existed that far back," Gallego says, "I don't think that I've ever been to a baseball game." The theory is that the card came out of a storage space they bought a few years back. It is not uncommon in their line of work to buy the entire contents of storage units for around $200. When she met with card trader Rick Mirigian, she found out what the card was-an 1869 advertisement with a picture of the first professional baseball team, the Cincinnati Red Stockings. "When I came to meet her and she took it out of a sandwich bag and she was smoking a cigarette, I almost fainted," Mirigian says. "They've uncovered a piece of history that few people will ever be able to imagine. That card is history. It's like unearthing a Mona Lisa or a Picasso." | ||
