Attic Find: $3M Worth of Baseball Cards

After coming upon a collection of 700 old baseball cards in his attic, an Ohio man put them aside. Two weeks later, he learned that they amounted to one of the biggest sports-card finds ever made—and were worth millions. The cards come from a 1910 series of which only a handful of cards still exist; those that do aren't in great condition. These, however, are almost perfect; an authenticator gave the set's Ty Cobb card a record 9 out of 10 for condition, with a Honus Wagner scoring a 10.

"Every future find will ultimately be compared to this," says an expert. Together, 37 of the cards are likely to score Karl Kissner $500,000 at an August auction, with the full set potentially woth $3 million. The cards belonged to Kissner's grandfather, Kissner says. He and a cousin found them as his family pored through generations of belongings after his aunt died. Most of the cards are set to be sold, with family members dividing up the money. "These cards need to be with those people who appreciate and enjoy them," Kissner tells the AP. (More baseball cards stories.)
