A 51-year-old man cleaning out the extensive contents of a house in Ohio that belonged to his grandfather found a soot-covered cardboard box that had been tucked away in the attic for a hundred years. Taking a look inside, he saw hundreds of baseball cards bundled with twine, including 16 mint-condition images of Ty Cobb. Half of the cards featured Hall of Famers like Cobb, Cy Young and Honus Wagner.

The cards with their vivid red and green backgrounds were likely given to Karl Kissner's grandfather, the owner a meat market, as a promotional tool to sell candy. They remained untouched for a century, making them the most significant and exciting find in collectible sports card history.

The 20 cousins who inherited the estate will split the 700 cards and auction money, which could add up to millions.
