PSA Grade Estimate
AI-Powered PSA Grade Predictor for Pokémon Cards
The PSA Grade Estimate is a free, instant prediction of the PSA grade your Pokémon card is most likely to receive if you submit it to PSA. It is built on top of our AI sub-grades for centering, corners, edges, and surface — the same four pillars PSA uses to assess condition — and shows you the most likely grade, a confidence rating, and a plain-English reason for the result.
Use it before you spend money on professional grading: it helps you decide which cards are worth submitting, which to keep raw, and which to re-photograph and try again.
What Is the PSA Grade Estimate?
When you scan a Pokémon card with PokeGrade, our AI evaluates four core attributes — centering, corners, edges, and surface — and produces an overall score. The PSA Grade Estimate takes that result one step further: it maps the AI scores to the most likely PSA grade (PSA 10, 9, 8, 7, or ≤6), assigns a probability spread across neighbouring grades, and explains the reasoning so you can sanity-check it yourself.
It is a pre-grade — not an official grade. PSA, BGS, CGC, and SGC remain the only authoritative sources for a slabbed grade. The PSA Grade Estimate is designed to give you a fast, free, realistic prediction so you can make smarter decisions before paying grading fees and waiting months for a return.
How the PSA Grade Estimate Works
Behind the scenes, the estimator is a transparent rule-based system layered on top of the AI grading model. Here is what it does:
1. Reads your AI sub-grades
It pulls the centering, corners, edges, and surface scores produced by the AI grading pass — the same numbers shown on your card detail page.
2. Picks a leading PSA grade
Using overall score thresholds (e.g. 9.5+ with all sub-scores ≥ 9.3 leads to PSA 10; 9.0–9.4 leads to PSA 9; 8.0–8.9 leads to PSA 8; and so on), it selects the most likely PSA grade.
3. Spreads probability across neighbours
A gaussian centred on your overall score distributes probability across the leading grade and one neighbour above and below, so you can see how confidently the model is leaning toward that grade.
4. Flags your weakest sub-grade
The lowest of your four sub-scores is highlighted as the main risk — typically the area most likely to drag your final PSA grade down.
5. Assigns a confidence rating
Confidence is High when both card sides are scanned and the sub-scores are tightly grouped, Low when image quality is poor or only the front was scanned, and Medium otherwise.
6. Explains itself
Every estimate ships with a short plain-English rationale so you can understand why the model picked that grade — no black box.
What the Sub-Grades Mean
PSA does not publish numerical sub-grades on a standard PSA label, but PSA graders evaluate cards using the same four pillars. PokeGrade exposes those sub-scores so you understand exactly where your card is strong and weak.
Centering
Measures how evenly the artwork sits within the borders. Off-centering is the single most common reason "pack-fresh" cards miss a PSA 10. Front and back are evaluated separately.
Corners
Sharpness and integrity of the four corner tips. Even tiny whitening dots can move a card down a grade.
Edges
Cleanliness of the perimeter — whitening, chipping, fraying, or dents along the four sides.
Surface
Print quality, gloss, scratches, print lines, dents, and stains — especially noticeable on holos and foils.
Accuracy & Limitations
The PSA Grade Estimate is built to be useful, not infallible. It is a model-based prediction, not a human grader's call.
- • It is most accurate when both the front and back of the card are scanned with sharp, evenly-lit photos.
- • Image quality flags (blur, glare, damage hints, low detection probability) automatically lower the confidence rating to "Low".
- • It cannot detect every defect a human grader would catch — subtle print lines, indentations visible only at certain angles, or alterations may be missed.
- • It cannot authenticate a card. If a card is fake, altered, or trimmed, the estimate is meaningless.
- • PSA grading itself is somewhat subjective; the same card sent twice can occasionally come back with different grades.
Treat the estimate as a strong signal, not a guarantee. Use it to triage your collection, decide what to submit, and learn what affects grades — not to set asking prices on raw cards.
How to Use the PSA Grade Estimate
Step 1 — Take good photos
Shoot the card top-down on a flat, neutral background with even lighting and sharp focus. Capture both the front and the back. Scanners at 300–600 DPI work even better. View the full photo guide.
Step 2 — Run a free scan
Submit your photos through the upload flow. Every signed-in user gets one free grading per day; paid credits unlock more.
Step 3 — Read the estimate
Check the most likely PSA grade, the probability spread, the highlighted risk attribute, and the rationale. The lower the confidence, the more cautious you should be.
Step 4 — Decide your next move
Send valuable cards predicted at PSA 9 or 10 for professional grading; keep low-prediction cards raw; re-shoot cards with "Low" confidence and try again. See which cards are worth submitting.
Frequently Asked Questions
How accurate is the PSA Grade Estimate?
It is most accurate when both the front and back of the card are scanned in clear, well-lit photos. Even then, it is a prediction, not a guarantee. PSA grading involves human judgement and the same card can come back with different grades on different submissions. Use the estimate as a strong signal to inform your decision, not a promise of a future grade.
Is the PSA Grade Estimate really free?
Yes. Every signed-in PokeGrade user gets one free grading per day, which includes the PSA Grade Estimate. Paid credits unlock additional scans and features but the estimate itself is included with every grading.
Does this replace PSA?
No. PokeGrade does not produce slabs, official grades, or population reports. The PSA Grade Estimate is a pre-grading tool that helps you decide whether a card is worth submitting to PSA in the first place. PSA, BGS, CGC, and SGC remain the only authoritative graders.
What's the difference between PSA, BGS, and CGC?
PSA is the most widely recognised TCG grader and typically commands the highest resale premiums. BGS (Beckett) always issues subgrades and is famous for its prestigious Black Label 10. CGC offers optional subgrades at a competitive price point. The PSA Grade Estimate predicts a PSA-style grade, but the underlying centering/corners/edges/surface assessment is meaningful regardless of which company you ultimately submit to. Compare grading companies in depth.
Why does the estimate sometimes show "Low" confidence?
Confidence is "Low" when the model has reasons to be cautious — the back of the card was not scanned, the image is blurry, there is heavy glare, the card looks damaged, or the AI could not detect the card cleanly. When confidence is Low, the safest move is usually to re-photograph the card and run another scan.
Will the AI catch a fake or altered card?
Not reliably. The PSA Grade Estimate assesses condition, not authenticity. If you suspect a card may be fake or altered, do an authenticity check first — see our guide on identifying fake Pokémon cards — before trusting any grade prediction. How to identify fake Pokémon cards.
Can I see the rationale behind the estimate?
Yes. Every PSA Grade Estimate includes a short plain-English rationale explaining why the model picked that grade, what the lowest sub-score is, and why confidence was set to Low, Medium, or High. There is no black box.
