Since 1970, the name 'Overstreet' has symbolized a vast knowledge of American comic books. While 'The Official Overstreet Comic Book Prize Guide' helps you learn about comic values, this third book in Gemstone's new 'How To' line teaches you the importance of condition (a factor that is often key to real collectability) and how to grade accurately. This book features the 10-point grading system, as well as exhaustive descriptions of Primary and Split Grades, examples of each grade with more than 200 full-colour images in all, articles on storage, preservation, and restoration, a look at the independent, third-party grading companies, and much more.
