Action Comics #1 Hidden Behind a Wall, Minnesota
When David Gonzales began renovating his Minnesota home, he had no idea what he would find: a copy of Action Comics #1, which introduced Superman to the DC universe. This comic book currently holds a considerable value for collectors, and Gonzales’ version was in great condition, netting him close to $200,000. It is amazing to think that the house’s original builders had been using it, along with other papers, to insulate their walls since 1938.
