We all have, or have heard, the horror stories of how entire shoeboxes of trading cards were tossed out by unwitting mothers.  Or how we  stuck Mickey Mantle's rookie card in the spokes of our bicycle wheels.

Not EVERYONE did this, however, which is why finding some of these old-time baseball cards is like Indiana Jones discovering the Ark of the Covenant.

One such discovery was made in Ohio that has recently been valued "conservatively" at over $3 million.

Karl Kissner of Defiance, Ohio defied the odds when he stumbled upon his grandfather's collection that dates back to 1910.  The collection of roughly 700 cards included a Gem Mint Honus Wagner that, when a similar card in worse condition, was sold at auction in 2007 for $2.8 million alone.

Other Hall-of-Famer's in the find include Cy Young, Ty Cobb and Connie Mack.
