DEFIANCE, Ohio -- Karl Kissner picked up a soot-covered cardboard box that had been under a wooden dollhouse in his grandfather's attic. Taking a look inside, he saw hundreds of baseball cards bundled with twine. They were smaller than the ones he was used to seeing.

But some of the names were familiar: Hall of Famers Ty Cobb, Cy Young and Honus Wagner.

His family had made what experts say is one of the biggest, most exciting finds in the history of sports card collecting, worth perhaps millions.

The cards are from an extremely rare series, circa 1910. The few known to exist were in so-so condition at best. But these are nearly pristine, untouched for more than a century.

"It's like finding the Mona Lisa in the attic," Kissner said.
