Question 1

How accurate are the grade predictions?

Accepted Answer

Our AI was calibrated on 24,000+ graded cards with documented outcomes. When we predict a 70% chance of PSA 9, roughly 70 out of 100 similar cards receive that grade. That's 97% prediction accuracy — far better than eyeballing it yourself. Most collectors overestimate their cards by a full grade on average due to optimism bias.

Question 2

What is the Capital Score and why should I care?

Accepted Answer

Capital Score is a 0-100 number that answers one question: should you submit this card or hold? It weighs your grade probabilities, card condition analysis, and grader fit into a single verdict. Scores 65-100 mean submit, 45-64 are borderline, and 0-44 mean hold. It takes the guesswork out of the most expensive decision in the hobby.

Question 3

Which grading company should I use for my card?

Accepted Answer

It depends on your card. PSA, BGS, CGC, and SGC all weigh centering, corners, edges, and surface differently — the same card can get different grades from each. Our Grader Fit Scores show you exactly which company's standards best match your card's strengths. A card that's a PSA 9 might be a CGC 9.5.

Question 4

What happens if I use all my monthly analyses?

Accepted Answer

The free plan includes 2 card analyses per month — enough to try it on your best cards. Each analysis gives you full grade predictions, probability matrices, defect detection, and Capital Score across all four grading companies. Need more? Starter gives you 30 analyses for $4.99/mo and Pro gives you 150 for $14.99/mo.

Question 5

What types of cards does it work with?

Accepted Answer

GradingMetric works with trading cards across all major categories: sports cards (baseball, basketball, football, hockey, soccer), Pokemon, Magic: The Gathering, Yu-Gi-Oh, and other collectible card games. Modern and vintage cards are both supported — from fresh-pull Scarlet & Violet to 1952 Topps.

Question 6

That centering you think is fine? It might cost you.

Accepted Answer

Most collectors can't tell the difference between 55/45 and 60/40 centering — but grading companies can, and it's often the difference between a 9 and an 8. Our AI measures centering, corners, edges, and surface from your photos, flagging defects with severity ratings. It catches what your eyes miss, including slight corner softness and edge whitening invisible in normal lighting.

Question 7

Is it worth submitting a $20 card for grading?

Accepted Answer

With all-in grading costs of $35-$50 for economy service, you need real confidence in a high grade to justify it. Most $20 cards aren't worth submitting unless they're strong PSA 10 or BGS 9.5+ candidates. Instead of guessing, our Capital Score calculates whether submission makes sense based on your card's actual condition — not your hopes.

Question 8

Will bad centering kill my grade? How do I know?

Accepted Answer

Centering is the #1 reason cards get lower grades than collectors expect. Each grading company has different centering tolerances — PSA is more forgiving than BGS, for example. Our AI measures your card's centering precisely and shows you how each grader would evaluate it. If centering is the weak point, Grader Fit Scores help you pick the most forgiving company.

Question 9

Does GradingMetric work with Pokemon cards?

Accepted Answer

Yes — Pokemon cards from all sets and eras, including Scarlet & Violet, classic WOTC-era cards, and Japanese Pokemon cards. Our AI analyzes centering, holo patterns, surface quality, and other Pokemon-specific factors that affect grades at PSA, BGS, CGC, and SGC.

Question 10

Can I really trust an AI over my own eyes?

Accepted Answer

Your eyes are great at spotting obvious damage, but they're terrible at measuring centering, detecting slight corner softness, or removing your emotional bias. Collectors overestimate their cards by about one full grade on average. Our AI was trained on 24,000+ cards with known outcomes — it doesn't have a favorite card, doesn't get excited about pulls, and doesn't convince itself that centering 'looks close enough.'

Question 11

How is this different from grading the card myself?

Accepted Answer

When you grade at home, you're making a subjective call with no data. You might look at centering and think 'that's fine' when it's actually 58/42 — enough to drop a full grade. GradingMetric gives you objective probabilities calibrated on real outcomes, defect detection that catches what you miss, and Grader Fit Scores that tell you which company to send to. It's the difference between guessing and knowing.
