ByCGN Staff
Pre-grading apps promise an answer to the most expensive question in the hobby: what will this card grade? We ran the leading options against cards with known professional grades.
How we tested
Same cards, same lighting, every app. We compared each app’s predicted grade to the professional grade on the slab.
Full disclosure
CardGrade is our parent company — this publication exists because they build grading tools. We show our test data so you can judge the comparison yourself.
