The verdict above is PSA's — the grader the population, the ROI table and the ladder on this page all use. Trader prices all three graders against each other and adds what the asking market is doing right now.

Trader plan and above →
  • PSA, CGC and Beckett side by side — each on its own population and fees, Beckett scored on the 9.5 its market pays for.
  • Lightly and moderately played — the same expected return for a copy that cannot gem.
  • Ask vs sold — what the live listings want, against what copies have really closed at.
  • Momentum — the 30-day median against the 90-day, per grade.
  • Where it sells higher — the Fanatics-versus-eBay premium, with the sale counts behind it.
  • Population history — the weekly PSA census, so you can see how fast 10s are arriving before you post the card.
