Comics are graded based on factors like condition, art quality, rarity, and completeness of the issue.
Comics are graded by considering multiple aspects. Firstly, the state of the comic book - is it in mint condition or does it have any damage? Then, the artistic merit - how well-drawn and visually appealing it is. Finally, its scarcity and whether all the pages are intact play a role.
Well, comic grading takes into account several things. The physical condition of the comic - no tears, stains or creases - is crucial. Also, the quality of the art, whether it's clear and detailed, matters. Rarity and if it's a complete issue or not are important too.
