We Analyzed 55,000 AI-Graded Pokémon Cards: Here Is What Actually Gets a 10
Collectors argue endlessly about gem rates, harsh graders and whether their card "should have been a 10". So we pulled the actual numbers from the TCGrader platform: 55,172 cards graded with numeric results, across Pokémon, sports cards, Yu-Gi-Oh! and more. Here is what the data says.
The headline numbers
- Average overall grade: 8.67
- Cards scoring a perfect 10: 6.7%
- Cards scoring 9.5 or higher: 24.4%
- Cards scoring 9 or higher: 56.3%
Read that middle number again. Even among cards that owners cared enough about to photograph and grade, fewer than one in fourteen earns a 10. If you're pre-grading a binder and mentally assigning tens to half of it, the data says you're going to be disappointed.
The subgrade that kills most cards
Every card gets four subgrades. Across all 55,000+ cards, they average:
| Subgrade | Average |
|---|---|
| Surface | 8.64 |
| Centering | 8.61 |
| Edges | 8.56 |
| Corners | 8.55 |
Corners are the weakest subgrade on average — and unlike centering, corner damage is usually handling damage, which means it's preventable. Cards that have ever been shuffled, binder-flipped or pocket-carried show it at the corners first. If you're buying raw cards to grade, zoom in on the corners before anything else.
Vintage grades far lower than modern
Sets tell a dramatic story. Modern sets graded on TCGrader in the last 90 days average around 8.6–8.9: Ascended Heroes (8.72 across 638 cards), Destined Rivals (8.81), Prismatic Evolutions (8.81), Chaos Rising (8.65).
Then there's Base Set: an average grade of 6.21 across 263 recent submissions. The Base Set Charizards we graded in that window averaged just 6.07.
That's not because vintage owners are careless — it's because 27-year-old cardboard that was actually played with carries whitening, edge wear and surface scratches that no modern pack-fresh card has. It's also why vintage grading economics are different: a mid-grade vintage card still carries real value, while a modern card below 9 usually doesn't justify its grading fee. We cover that decision in Is Your Pokémon Card Worth Grading?
Pokémon dominates, sports cards grade lower
Pokémon makes up the overwhelming majority of graded cards on the platform. Sports cards average notably lower (7.78) — older stock, more handling, and stricter surface visibility on glossy modern sports finishes.
What this means for your submissions
- Calibrate to 8.67, not to 10. The average card — including cards people believed in enough to grade — lands under 9.
- Check corners first. The most common grade-killer is also the easiest to spot with a phone camera.
- Grade vintage on value, modern on condition. A 6 on a Base Set card can still be worth slabbing; a 6 on a modern card never is.
- Pre-grade before you pay. Every card in this dataset was graded in seconds from photos. Running your cards through TCGrader's AI grading before a paid submission tells you which ones have a genuine shot — free users get their first grade on us.
We'll keep publishing platform data as the sample grows. For the methodology behind the grades themselves, see How AI Card Grading Works.
