  • 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.
