Why prices differ
TCGplayer's figure is what sellers are asking on their marketplace, not what copies sold for — an asking price sits above a completed sale because it is the start of a negotiation, not the end of one. Our price comes from those same completed sales, adjusted to Near Mint — the median below mixes every condition together, and most copies that change hands are played rather than mint.

Compare graders, and the live market
The verdict above is PSA's — the grader the population report, the ROI table and the price ladder on this page all use. Trader prices all three graders against each other and adds what the asking market is doing right now.
- PSA, CGC and Beckett side by side — each on its own population and its own fees, with Beckett scored on the 9.5 its market actually 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.
The odds
Serperior is a Commoncard — a guaranteed slot in every pack, not a rarity gamble, so there's no pull-odds figure for it.
Estimates only. Pack odds come from CardTrack's pack model (the same one behind the pack simulator) — not an official rate. Grading odds are the real cumulative PSA population, which skews toward nicer, resubmitted copies, so it overstates the true first-submission gem rate. Full grade-by-grade breakdown below.
Grade-by-grade ROI & risk-adjusted outcomesNet vs raw per target grade, plus the probability-weighted distribution
| Target grade | Est. value | Grading fee | Net vs raw | Multiple |
|---|---|---|---|---|
| PSA 9 | $29.05 | $70 | −$46 | 5.5× |
| PSA 8 | $25.00 | $70 | −$50 | 4.8× |
Net = graded value − raw value − grading cost (tier fee + ~$20 round-trip shipping), using PSA fees as of 2026-08-26; the paused PSA Value tier is excluded so this isn't overstated. Real outcome depends on the grade achieved; PSA 10 is best-case.

Real graded population from PSA, CGC, BGS & TAG — a lower gem rate means a Serperior 10 is harder to pull.
