Comic Book Grading Scale: The Complete 0.5–10.0 Chart
Every comic grade explained, from Gem Mint 10.0 down to Poor 0.5 — what each number means, the defects that define it, and how to find your comic's grade instantly.
The comic grading scale, explained
Comic books are graded on a numeric scale from 0.5 (Poor) to 10.0 (Gem Mint), based on the Overstreet/Sheldon standard. The grade reflects a comic's physical condition — cover, spine, corners, staples, pages, and centering. Grading companies like CGC and CBCS use this scale, and so does ComicMintAI's AI comic grader. Because value rises steeply with grade, knowing where a book falls is the single most important factor in what it's worth.
Full comic grade chart (10.0 → 0.5)
| Grade | Label | What it means |
|---|---|---|
| 10.0 | Gem Mint (GM) | Virtually perfect. Flawless cover gloss, square spine, sharp corners, and perfect centering. Essentially as it left the printer. |
| 9.9 | Mint (MT) | Nearly perfect with only the most trivial manufacturing flaw visible under close inspection. |
| 9.8 | Near Mint/Mint (NM/M) | The modern key benchmark. Negligible handling defects; the grade most collectors and sellers target. |
| 9.6 | Near Mint+ (NM+) | Outstanding copy with a couple of very minor defects, such as the slightest spine stress. |
| 9.4 | Near Mint (NM) | Excellent eye appeal with minor defects only — a tiny corner blunt or light spine wear. |
| 9.0 | Very Fine/Near Mint (VF/NM) | Near-excellent with a few minor defects beginning to show, still bright and attractive. |
| 8.0 | Very Fine (VF) | An attractive copy with moderate wear — minor spine stress, slight corner blunting, light surface wear. |
| 6.0 | Fine (FN) | An above-average used copy. Multiple minor to moderate defects but still complete and presentable. |
| 4.0 | Very Good (VG) | A well-read copy with noticeable wear: spine roll, creases, minor tears, soiling, but structurally sound. |
| 2.0 | Good (GD) | A complete but heavily worn reading copy. Significant defects such as creasing, tears, and soiling. |
| 1.0 | Fair (FR) | Heavily worn and possibly soiled or damaged, but largely complete with the cover attached. |
| 0.5 | Poor (PR) | Severe damage, may be missing pieces, brittle, or heavily restored. The lowest collectible grade. |
Comic defect glossary
Graders dock points for specific defects. The most common ones to know:
- Spine tick: A small color-breaking stress mark perpendicular to the spine.
- Spine roll: A curve along the spine from the book being stored open or rolled.
- Color break: A crease or bend severe enough to break the cover's ink, exposing white beneath.
- Foxing: Brown age spots caused by moisture and oxidation on paper.
- Married: A copy assembled from parts of two different books (e.g., a replaced cover or pages).
- Restoration: Any non-original work — color touch, re-glossing, tear seals, piece fill — which lowers value vs. an unrestored copy.

Frequently asked questions
What does 9.8 mean in comic grading?
A 9.8 is "Near Mint/Mint" — a nearly perfect comic with only negligible handling defects. It is the benchmark modern collectors and sellers target because the jump from 9.4 to 9.8 often multiplies a book's value.
What is the highest comic book grade?
The highest grade is 10.0, called Gem Mint — a virtually flawless copy. Above 9.8, perfect copies are extremely rare.
What is the difference between VF and NM?
Very Fine (8.0) shows moderate, visible wear and still looks attractive, while Near Mint (9.4) has only minor defects and much stronger eye appeal. The gap usually means a meaningful difference in market value.
Who created the comic grading scale?
The 0.5–10.0 numeric scale is based on the Overstreet/Sheldon grading standard widely adopted by grading companies such as CGC and CBCS, and now used by AI graders like ComicMintAI.
Can I grade my comic on this scale myself?
You can estimate a grade by inspecting the cover, spine, corners, staples, and pages against this chart. For an objective grade, ComicMintAI assigns a grade on this exact scale from a single photo in seconds.
