The Problem
Grading the wrong card gets expensive.
Submission fees, shipping, insurance, and months of waiting can turn a promising card into a losing decision. Most collectors are still relying on guesswork, inconsistent opinions, or a quick look under a desk lamp.
Grading fee
Per-card cost, paid up front
Shipping and insurance
Both directions, declared value
Selling fees
Marketplace and payment cuts
Time without the card
Weeks to months in queue
Risk of a lower grade
A 9 can change the whole math
Gems helps you make the decision before you spend the money.
How It Works
From raw card to confident decision.
Scan the front and back.
Gems guides you through taking clear, consistent images and automatically detects glare, blur, sleeves, shadows, and poor angles.
See what the eye misses.
Our AI evaluates centering, corners, edges, whitening, print defects, and visible surface issues using card-specific grading criteria.
Submit with confidence.
Review grade probabilities, expected value, identified defects, and a clear recommendation to submit, sell raw, or inspect further.
Your Grade Report
More useful than a single number.
Gems shows the range of possible outcomes, why the card may receive each grade, and whether the numbers justify submitting it.

Why Gems
Built to answer the question that matters.
Is this card worth grading?
Grade Probabilities
See the estimated likelihood of receiving a PSA 10, PSA 9, or lower grade instead of receiving one overconfident prediction.
Defect Mapping
Understand which corners, edges, centering issues, or visible surface defects may hold the card back.
Submission Economics
Compare raw and graded values after grading fees, shipping, insurance, and selling costs.
Grade Verification
Record the final PSA result to compare it with the original prediction and help improve future analysis.
Not Another Card Scanner
A submission decision engine.
Other tools identify cards or produce a condition score. Gems is designed around the complete decision: what grade is realistic, what defects matter, how confident the prediction is, and whether submitting makes financial sense.
