Upload a photo and CardGrade Intelligence (CGI) predicts your PSA 10, 9 & 8 odds in about 60 seconds — 47 inspection points across 16 zones, 92.8% accuracy, trained on 32,000+ graded cards. Pre-grade your cards before PSA does.
Free to start, no signup required. Free 3-day trial to unlock full results — card on file, $0 upfront.
CardGrade Intelligence inspects the same four factors PSA graders use — across 16 zones — to estimate whether your card hits PSA 10, 9, or 8.
Front and back alignment against the 55/45 PSA 10 threshold — the #1 reason cards miss gem.
Sharpness and any softening, fraying, or whitening at all four corners.
Edge whitening, nicks, and chipping detected under simulated lighting.
Scratches, print lines, and gloss loss — defects often invisible until slabbed.
Of 7,985 cards CGI has analyzed, 3,094 (38.7%) scored in the gem mint range (9.5-10) — but 27.3% landed below PSA 8, where the grading fee usually costs more than the value it adds. The predictor tells you which side of this curve your card falls on before you submit.
Across all 7,985+ cards, corners consistently scores the lowest at 8.69 average — the single sub-grade most likely to cap your card at PSA 9. The predictor weighs it heavily, and you can pre-check it with our free centering tool before submitting.
Your predicted PSA grade depends heavily on what you are submitting. Pokemon and TCG cards consistently outperform sports cards in our dataset, and CGI factors card type into every prediction.
| Card Type | Avg Grade | Cards Analyzed |
|---|---|---|
| Football | 9.01 | 480 |
| Basketball | 8.54 | 67 |
| Other | 8.51 | 298 |
| Sports (Other) | 8.36 | 276 |
| Baseball | 7.97 | 130 |
The era of your card is the single biggest predictor of your PSA 10 chances. This data comes from GemRate and Cardlines analysis of PSA population reports — context the predictor reflects in its odds.
| Decade | Sports Gem Rate | TCG Gem Rate | Your Odds |
|---|---|---|---|
| 2020s | 41.2% | 60.8% | Good |
| 2010s | 34.8% | 37.2% | Moderate |
| 2000s | 19.8% | 10.5% | Low |
| 1990s | 11.4% | 7.5% | Very Low |
| 1980s | 6.8% | 8.4% | Unlikely |
| 1970s |
Upload your card and let CGI predict a PSA grade in ~60 seconds. Costs nothing to start — saves you $20-50 on cards that won’t gem.
Predict my PSA grade →PSA requires 55/45 or better on the front and 75/25 on the back. Even 60/40 kills a PSA 10.
Use centering tool →Tilt the card under a bright light at different angles. Edge whitening is the second most common defect after centering.
Read edge guide →Use clean hands or gloves. Store in penny sleeves + top loaders immediately. Surface scratches are invisible until slabbed.
Read prep guide →Our PSA 10 Chances report pairs your predicted grade with real gem-rate data from 32,000+ AI-analyzed cards — so you know the odds before you ever upload.
See your PSA 10 chances →Upload a clear photo of your card and CardGrade Intelligence (CGI) analyzes it in about 60 seconds. CGI runs 47 inspection points across 16 zones — covering centering, corners, edges, and surface, the same four factors PSA graders evaluate — and returns a predicted PSA grade with your PSA 10, 9, and 8 odds. It is 92.8% accurate and trained on 32,000+ graded cards.
Yes. You can upload a photo and see a predicted PSA grade with your PSA 10/9/8 odds at no cost and with no signup to get started. The deeper output — your full 16-zone breakdown, BGS and CGC predictions, market value at every grade, and a shareable public grade certificate — unlocks with the free 3-day trial (card on file, $0 charged upfront).
CGI is 92.8% accurate and backed by a 2-grade accuracy guarantee. It was trained on 32,000+ already-graded cards, so its predictions reflect how real cards actually scored at PSA. No AI tool can guarantee a final PSA grade — final grading is subjective — but pre-grading first tells you whether a card is worth the submission fee before you mail it.
Centering. Across the 32,000+ cards CGI has analyzed, centering consistently scores the lowest of the four sub-grades. A card that is otherwise flawless frequently caps at PSA 9 because the front is off-center past the 55/45 threshold. That is why the predictor weighs centering heavily when estimating your PSA 10 odds.
Yes. CGI predicts grades for Pokemon and other TCG cards as well as sports cards. In our dataset, modern TCG cards gem at a higher rate than sports cards, so your predicted PSA 10 odds depend heavily on card type and era — the predictor accounts for both.
