You never know what you will find when you're cleaning out a family member's home after they pass away.

A family has hit a baseball memorabilia jackpot after discovering not one, but seven Ty Cobb baseball cards tucked away in an old paper bag, The Associated Press reported.

The cards were printed from 1909 to 1911 and were uncovered as an unidentified family was cleaning out a dilapidated house of a great-grandfather who died.

The home was in a unspecified location, only said to be in the south.

The cards are part of the T206 series and were rated between 3.5 and 4.5 for their condition on a scale of 1 to 10. Experts said that's not bad for a more than century-old card.

The front of the card shows Cobb in a Detroit Tigers' uniform, the back says "TY COBB - KING OF THE SMOKING TOBACCO WORLD," The AP reported.

There were believed to be 15 T206 Cobb cards still in existence before this discovery, The AP reported.

Experts believe the seven cards could be worth more than $1 million.
