What does pre-grading mean for trading cards?
Pre-grading is estimating a card's expected PSA / BGS / SGC grade before sending it to those services. It's a screening step that saves money: with $25–$150 grading fees, you don't want to submit cards that will grade below 9. CardMintAI's AI predicts your PSA grade in 2 seconds from a single photo.
Can an app predict my PSA grade?
Yes. CardMintAI is an app to predict PSA grades. The AI evaluates centering, corners, edges, and surface — the same four attributes PSA evaluates — and outputs a predicted grade from 1 to 10. Free to try, no credit card required.
How accurate is AI pre-grading vs an actual PSA grade?
Our AI pre-grading achieves 95% alignment with actual PSA outcomes, with most predictions within ±1 grade point. That's reliable enough to make submission decisions — submit the 9–10 candidates, hold the rest.
Is there a free pre-grading app for cards?
Yes. CardMintAI's pre-grading is free to try with no credit card. Two free grades, full PSA-standard analysis (centering, corners, edges, surface), same AI as paid users.
How do I pre-grade Pokémon cards at home?
Photograph the card front and back in even lighting on a dark, non-reflective surface. Upload to CardMintAI. The AI returns a predicted PSA grade with sub-grades in 2 seconds. Works for any TCG — Pokémon, MTG, Yu-Gi-Oh — plus sports cards.
Should I pre-grade my cards before sending to PSA?
Almost always yes. PSA fees ($25–$150/card) only pay off when the card grades 9 or 10. Pre-grading reveals which cards are likely to hit that bar. If you have 100 cards and 30 are likely PSA 9–10, pre-grading saves you $1,750+ on cards that would've graded lower.
What's the difference between pre-grading and grading?
Pre-grading is an estimate done from a photo — fast, free, non-binding. Grading (by PSA, BGS, SGC) is the official assessment with encapsulation and a serial number — slow, paid, market-recognized. Use pre-grading to filter; use grading on the winners.
How long does pre-grading take?
About 2 seconds per card with CardMintAI. Batch uploads grade hundreds of cards in a few minutes. Compare to PSA: 65+ business days economy, 30 days regular.
