Grading check
Measure a card's centering from a photo against PSA's standards. It runs on your phone: the photo is not uploaded. Beta: a guide before you pay to grade, not a grade.
Front centering
Free- Out of the sleeve, flat on a dark, plain surface.
- Phone straight above it, the card filling most of the photo.
- No glare: flash off, and tilt away from bright lights.
