DOn’t let anyone fool you and tell you baseball cards aren’t worth anything anymore.

A family that wishes to remain anonymous told card experts that they found a set of T206 series cards, which were printed from 1909 to 1911, in an old paper bag in the dilapidated house of a deceased great-grandfather, who lived in an unspecified location in the south.

The cards of the Detroit Tigers Hall of Famer have “Ty Cobb — King of the Smoking Tobacco World” printed in capital letters in green ink on the back. The value of the cars is said to be an estimated $1.3 milion.

“I am not sure if any other baseball card find is more remarkable than this new discovery,” said Orlando, president of Professional Sports Authenticator in Newport Beach, in a statement. “This is one of the greatest discoveries in the history of our hobby.”

The first authenticator to view the cards said he was skeptical, but like Orlando was able to verify that the cards were legitimate. On a scale of 1-10, with the latter being mint condition, the cards were given ratings of 3.5 to 4.5, which is good for a century-old card.
