Why it pays for itself
One avoided PSA-9-instead-of-10 covers a year of Pro.
Centering is the #1 reason 9s aren't 10s. We measure it on real-world buying photos — perspective corrected first, so a tilted shot still reads true.
Why MintPick
Built for flippers, not flatbed scanners.
02
No fake centering
We correct camera angle first, so a tilted photo still reads true geometry.

Who this is for
§ 01 / 04Three ways collectors put it to work.
Flippers
Spot the keeper before the next bidder does.
Screenshot a listing, paste it in, see centering in under ten seconds. Stack three copies side by side and buy only the one that grades.
Sellers
Price inventory off real geometry, not a gut call.
Measure what you own, mark it up honestly, and keep the good copies. Export clean readouts — no watermark — straight into your listing photos.
Graders
Pre-screen a submission batch in minutes.
Check centering before you pay for grading. Re-edit any saved scan, compare a whole batch on one Board, kill the obvious fails up front.
Why perspective matters
Measure the card, not the camera angle.
Most buying photos are handheld, tilted, badly cropped, or shot in a hurry. We rectify first so the readout follows the card geometry, not the shot.
FAQ
Short answers for collectors.
Does MintPick predict a PSA grade?
No — it measures centering only. PSA grades on four factors (centering, corners, edges, surface). We treat MintPick as a pre-grading triage tool: catch the off-center copies before you pay for grading, since centering is the most common reason 9s aren’t 10s.
Is MintPick free?
Yes for unlimited single-card scans. Pro is $9.99/month or $89.99/year on the web (save 25% annually) and unlocks Stack comparison, paste from clipboard, unlimited Board, re-edit, and clean exports.
Can MintPick work on eBay screenshots or card-show photos?
Yes. It is built for listings, screenshots, and quick handheld shots, not only perfectly flat scans.
Why is perspective correction important?
Because handheld photos skew the card. If you measure before rectifying, camera angle can fake the centering.
What does the AI do automatically?
It rectifies the card, then uses our trained models to find all four corners and border lines on the corrected image.
Do I need an account or a flatbed scanner?
No. You can start from a phone photo or screenshot, and your first scans do not require signup.
