Every graded comic wears a number between 0.5 and 10.0, and that single figure can swing a book’s value by thousands of dollars. But most collectors only really understand the top two grades. Here’s what every meaningful grade on the CGC scale actually means — and how each one moves the price.
Quick Answer
The CGC scale runs 0.5 to 10.0. In practice, 9.8 (Near Mint/Mint) is the market benchmark. A 9.6 typically brings 50–70% of a 9.8, a 9.4 around 35–55%, and a 9.0 (Very Fine/Near Mint) roughly 25–40%. Below 8.0, copies are bought to read or to fill a slot rather than as investments. Scarcity and demand for each specific book shift these ratios.
| Grade | Label term | What it means | Typical value vs 9.8 |
|---|---|---|---|
| 10.0 | Gem Mint | Effectively flawless; almost never awarded on vintage | Multiples of 9.8 |
| 9.9 | Mint | One tiny flaw away from perfect; very rare | 150–400%+ |
| 9.8 | NM/M | The market benchmark for high-grade collecting | 100% (baseline) |
| 9.6 | NM+ | A hair below benchmark; often the value sweet spot | 50–70% |
| 9.4 | Near Mint | Minor handling visible on close inspection | 35–55% |
| 9.0 | VF/NM | Attractive, light wear; strong display copy | 25–40% |
| 8.0 | Very Fine | Noticeable wear but eye-appealing | 15–30% |
| 6.0 | Fine | Solid mid-grade; a reader/filler for keys | 8–18% |
Ratios are observed market averages; scarce, high-demand keys compress the gaps while common books widen them.

The Top of the Scale: 9.8, 9.9, and 10.0
A CGC 9.8 is where serious high-grade collecting lives. It’s not perfect — it can have a couple of tiny, barely-perceptible flaws — but it’s the grade the market treats as the standard for “the best realistically obtainable copy” of most books. Above it, 9.9 and 10.0 exist but are so scarce on vintage that they trade as trophies, often for multiples of the 9.8 price.
The Value Sweet Spot: 9.6 and 9.4
This is where savvy buyers spend. A 9.6 usually looks identical to a 9.8 to the naked eye but trades for 50–70% of the price. A 9.4 drops further. If you’re buying to enjoy and display rather than to chase census-topping investment copies, the 9.6/9.4 tier delivers most of the visual quality for a fraction of the premium.
Mid-Grade: When 9.0 and Below Make Sense
For expensive keys, a mid-grade slab is often the only sane entry point. A 9.0 VF/NM of a five-figure book can cost a quarter of the 9.8 while still being a genuinely attractive copy. Below 8.0, you’re generally buying to read, to complete a run, or to own a key you couldn’t otherwise afford — all perfectly legitimate reasons, just not appreciation plays.
How to Use the Scale When You Buy
Decide your goal first. Chasing investment-grade appreciation? Stay at 9.6 and up on scarce keys. Building a display collection? The 9.4–9.0 band stretches your budget. Filling a run or grabbing a grail? Mid-grade is your friend. Then check the CGC census for that specific book — a “common” grade on one title can be genuinely scarce on another, and that’s what really sets the premium.
Bottom Line
The CGC number is shorthand for condition, but its effect on price is all about scarcity and demand for the individual book. Learn the tiers, read the census, and you’ll know instantly whether a listing is a fair deal or a trophy tax.
