Attorney Matt Murdock and his alter ego, Daredevil, have been fighting crime between the pages of Marvel Comics since the character's debut in 1964. Blinded by a radioactive substance that heightened his other senses, the superhero is readily identifiable in his all-red uniform that makes him resemble a devil, complete with horns on his uniform's mask. Daredevil comic books can be quite valuable, especially Daredevil issue 1, published in April of 1964. Similar to other collectibles, comic books receives grades based on condition. Mint-condition comic books are usually in unread condition, featuring stiff spines and pages that are crease-free. The comic books are often kept in plastic or Mylar bags, and the comics themselves are free from stains, markings, and tears on the front and back covers and inner pages. Another valuable comic book is Daredevil issue 168, which features the first appearance of Daredevil's love interest and sometimes nemesis, Elektra.
