PSA Pre-Grading — Know Your Grade Before You Pay the Fee
A PSA submission costs $25–$150 per card and takes weeks, and you don't find out the grade until after you've paid. CardMintAI's AI pre-grades your card first — centering, corners, edges, and surface — and predicts the PSA grade in about two seconds, with 95% alignment to real PSA outcomes. Submit only the cards worth it. 1 free grade, no credit card.

The Pre-Grading Step That Protects Every PSA Submission
Predict the PSA grade at home so you never pay a submission fee on a card that won't come back worth it
PSA-Grade Prediction
CardMintAI scores your card on the same four attributes PSA does — centering, corners, edges, surface — and returns a predicted PSA grade so you know whether it's a 9, a 10, or a pass before you submit.
Submit-or-Skip Verdict
Every report answers the only question that matters at submission time: is this card worth the PSA fee? Turn an expensive guess into a clear yes or no.
Centering & Surface Detail
See the exact centering percentages and surface flaws that decide PSA 9 vs PSA 10 — the details that quietly sink submissions when you can't see them in hand.
Works for Every Category
Pre-grade Pokémon, Magic, Yu-Gi-Oh, One Piece, and sports cards for PSA, BGS, or CGC — the pre-grading logic is the same across every service and game.
Batch Before You Bulk-Submit
Prepping a bulk PSA order? Pre-grade the whole stack first and only mail the winners, so your per-card fee goes toward cards that will actually gain value.
Free First Pre-Grade
Test it on your own card free, with no credit card, and see the full subgrade report before you decide to submit anything to PSA.

What is PSA pre-grading?
PSA pre-grading is predicting the grade PSA would assign to a card before you actually submit it. CardMintAI analyzes a photo of your card — centering, corners, edges, and surface — and returns a predicted PSA grade in about two seconds, so you can decide whether the card is worth the $25–$150 submission fee before you pay it.
How accurate is AI PSA pre-grading?
CardMintAI is trained on thousands of professionally graded cards and aligns with real PSA outcomes about 95% of the time within a grade. It's built as a pre-screening step to tell you which cards deserve submission — it doesn't replace the official PSA grade, which is what drives resale value.
Does PSA offer its own pre-grading service?
PSA's official grade is only issued after you submit and pay. Pre-grading is what you do beforehand to predict that outcome. Using an AI pre-grader like CardMintAI first lets you avoid paying PSA to grade cards that will come back too low to be worth the fee.
How much can PSA pre-grading save me?
PSA fees start around $25 per card and climb to $150+ for higher tiers and faster turnaround. If you pre-grade a 20-card batch and the AI flags that half won't hit the grade you need, you skip those and save hundreds — often more than a full year of CardMintAI on a single submission.
Can I pre-grade cards for PSA for free?
Yes. Your first pre-grade is free with no credit card required, and it includes the complete report: a predicted PSA grade plus centering, corner, edge, and surface subgrades. You can validate the accuracy on a card you already know before paying for more.
