Comic book grading is a system used to evaluate the condition of comic books. This grading helps collectors and buyers understand the quality and value of a comic. Grades typically range from 0.5 (poor) to 10.0 (gem mint), with various levels in between. Factors considered include the comic's cover, pages, and overall appearance. Professional grading services, like CGC (Certified Guaranty Company), assess comics and assign a grade. They encapsulate the comic in a protective case, ensuring its condition is preserved. This grading process is essential for collectors, as it influences the comic's market value and desirability.
