Should you grade
this card?

ZeroPop is an AI-powered card grading app for iOS, Android, and the web that predicts what PSA, BGS, and CGC will grade your card before you submit. It is not an official grading company. The predictions are AI estimates, and every grade shows the photos, measurements, and reasoning it came from so you can check the call yourself. Use it to decide which cards are worth the $25+ PSA fee and which to sell raw.

We do not publish an accuracy percentage against PSA yet, because we have not run the study that would earn one. What you get instead is the evidence: every grade shows the photos it was read from with the measured region drawn on them, a close-up of each corner, the recorded defects, and the reasoning behind each sub-grade for corners, edges, surface, and centering. Centering is reported as L/R and T/B ratios, the same way PSA describes it, so you can check the call before you pay to submit.

ZeroPop calculates the expected profit at every PSA tier (10 down to 5), the break-even grade you need to clear, and the recommended submission level (Value, Bulk, Economy, etc.). If the break-even grade is higher than what your card scans, the app recommends selling raw instead.
