As of 2015, the Wizard Comic Price Guide is no longer a good resource for valuing vintage comics because it is no longer in print. The Overstreet Comic Book Price Guide is the most widely respected reference for comic book collectors who wish to determine the value of their comics.
Often called the Bible for comic collectors, the Overstreet Comic Book Price Guide provides historical comic book facts, valuable marketplace information, and accurate, up-to-date pricing recommendations for vintage comics. This vital reference is available in both print and e-book formats.
Robert M. Overstreet, an avid collector of comic books and arrowheads, first published the Overstreet Comic Book Price Guide in 1970. The guide was an immediate success and quickly became the most authoritative resource for comic book enthusiasts across the country.
In contrast, Wizard: The Comics Magazine, previously known as Wizard: The Guide to Comics, remained in print only from 1991 to 2011, and it struggled for many years before it was discontinued. The publication never unseated Overstreet's position as the most reputable guideamong comic collectors. A free online PDF publication titled Wizard World replaced the print version of the magazine in 2011, but it is not a generally respected valuing guide for comic books.
