OK, time to start visiting all your elder relatives and going through their attics. A man in Tennessee found a bunch of unopened baseball, football and basketball cards that could end up fetching over $1 million in an auction by Mile High Card Company

From the article on Forbes

The caller revealed that he had boxes of early 1960s Topps and Fleer football, 1959 Fleer Ted Williams, and many other sealed packs. They all had been found fairly recently in his 90-year-old aunt's attic in Tennessee after his uncle passed away. For more than half a century, the uncle had kept packs untouched in a Stroh's beer box almost as old as the cards themselves.

By the way, there was also a 1961 Fleer Basketball unopened box of wax packs, probably containing the rookie cards of Hall of Famers Wilt Chamberlain, Jerry West, and Oscar Robertson.

Not only that, but the person who found the cards also stumbled upon a box with 19 packs of 1948 Bowman cards, the first-ever set of baseball cards. Reportedly this box on its own is worth $500,000 and the total haul for the man who found these cards by accident could well be over $1 million. 

There are a lot more details in the Forbes story, so definitely head over there if interested. I'm gonna start finding some attics to search.
