Protect and Organize Your Graded Comic Books
3
To grade comic books, trusted companies such as the Certified Guaranty Company (CGC) and the Comic Book Certification Service (CBCS) will evaluate comic books, grade them on a 1 to 10 scale, and encapsulate each comic in a rigid plastic frame, called a slab. A grade of 10 is a flawless comic, but that grade is rarely awarded. These comics will be protected for years to come, and a graded comic will have a higher secondary market value. The obvious negative of getting a comic slabbed is you cannot view the interior pages without breaking the slab, and the risk of damaging the comic in the process.
