What 1,067+ AI-analyzed cards reveal about grading bottlenecks, which cards are actually worth the $15–25 submission fee, and where collectors waste money
Based on cards analyzed through CardGrade's 47-point AI inspection system. Industry data sourced from GemRate, CLLCT, and Ken's Cool Cards.
12.5 million cards were submitted to physical graders in 2025. At $15–25/card, that's $187M–$312M spent. But how many were actually worth grading?
| Company | Volume (2025) | Market Share | Bulk Cost | Turnaround | Resale Premium |
|---|---|---|---|---|---|
| PSA | 8.2M | ~70% | $25/card | 75-95 days | +65% |
| SGC | 2.3M | ~15% | $15/card | 40-50 days | +40% |
| BGS | 1.1M | ~10% | $18/card | 75+ days | +35% |
| CGC | 850K | ~5% | $15/card | 40-80 days | +30% |
| TAG | N/A | <1% | $19/card | 30-45 days | Emerging |

11.4% of cards we analyzed would likely grade below a PSA 8 — the threshold where grading fees typically exceed the value they add to the card.
The cost of guessing wrong
At $25/card for PSA bulk, 122 cards in our sample would grade below 8 — meaning $3,050 in grading fees spent on cards that come back worth less than what you paid to grade them.
We compared CardGrade's AI predictions to actual grading outcomes tracked by GemRate, the industry's most comprehensive grading analytics platform.
1,067+ cards scanned
Across all cards scanned — including cards collectors wouldn't normally submit for grading
8.2M+ PSA submissions tracked
Among cards people chose to submit — already pre-selected as their best candidates
GemRate's ~43% gem rate reflects cards that collectors already believed were worth the $25 submission fee. CardGrade's 27.9% rate is across all cards scanned — including the 11.4% that would likely grade below a PSA 8.
That 15.1-point gap shows why pre-screening pays for itself. The 43% gem rate at PSA exists because experienced submitters already filter out their worst cards before paying $25 each. Without that filter, most cards won't come close to gem status.

Centering is the #1 grade-limiting factor, averaging 8.79 vs 9.31 for Surface.
Tip: Before submitting, check centering first — it's the most common reason cards miss higher grade thresholds.
Football cards grade highest on average at 9.09, based on 147 cards analyzed. Category matters when deciding what's worth submitting.
Average spread of up to 0.6 grade points between the most lenient and strictest grading company.
Choosing the right grading company can mean the difference between a 9 and an 8 — which often translates to 2–3x in resale value for popular cards.
Cards grading 9.5+ are worth 0.1x more than 8.0–8.4 cards on average.
Based on estimated market values at time of grading. Values reflect averages across all card types.

1,067+ cards analyzed through CardGrade.io, spanning all major card categories including Pokemon, sports cards, and TCGs. Data reflects gradings completed through March 2026.
Each card undergoes a 47-point inspection using computer vision, analyzing centering, corners, edges, and surface condition. The model generates predicted grades for PSA, BGS, and CGC based on each company's published grading standards.

All data is from cards analyzed through CardGrade.io's AI grading platform. Each card undergoes a 47-point inspection analyzing centering, corners, edges, and surface condition. Industry data (volumes, market share) comes from GemRate, Ken's Cool Cards, and CLLCT.
CardGrade's AI is trained on professionally graded cards and uses computer vision to detect the same defects human graders look for — centering offsets, corner wear, edge whitening, and surface scratches. It's designed as a pre-screening tool: identify which cards are worth the $15-25 physical submission fee before you spend the money.
PSA 8 (NM-MT) is generally the breakeven point — below that, the $15-25 grading fee often costs more than the value bump you get from having a slab. Cards predicted below 8 are usually better left raw or in penny sleeves.
Each grading company has its own standards and weighting. PSA is generally considered more lenient, BGS the strictest (especially at the 9.5+ level), and CGC falls in between. This is why our predictions differ by company — the same card can legitimately receive different grades depending on who grades it.
