Collectibles Facts

In 2011, a couple bought a box of textbooks for $10. Inside, they found a 25-cent bill signed by the president of the Republic of Texas, Sam Houston, and subsequently sold it for $63,250.

Karl Kissner was cleaning out his late grandfather's attic in Defiance, Ohio when he found a dusty box. Inside were roughly 700 baseball cards from 1910 - including 16 Ty Cobbs and a Honus Wagner - in near-perfect condition, untouched for a century. The collection was valued at $3 million.
