Relatives considered tossing the torn paper bag they found in the southern home of their late great-grandfather earlier this year. It's a good thing they didn't: Buried beneath old postcards and papers was one of the biggest discoveries of rare baseball cards ever. On Wednesday, memorabilia expert Joe Orlando confirmed the seven cards featuring Hall of Famer Ty Cobb are from a 1909-1911 American Tobacco Company set and worth "well into the seven figures," reports NBC News. Only 15 were previously known to exist. "Finding one of these cards is news," Orlando tweeted. "Finding seven in one shot is ridiculous." (An Ohio man found a card collection worth $3 million.)
