FOUND IN A WALL

 A copy of Action Comics No.1, wherein Superman debuted in 1938, was found in the wall of a Minnesota house built during the same year. Found during a renovation, it sold for $175,000, according to comic book seller ComicConnection. It might’ve brought more, but it was graded only 1.5 out of 10 because of a detached cover; a near-mint copy graded at 9.0 sold for $2.16 million in 2011.
