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
Cloyster is a Holo / V / ex in Expedition Base Set — the pack's hit slot lands on Holo / V / ex 33% of the time, split across 32 holo / v / ex cards in the set, so pulling this exact card is roughly 1 in 97 packs.
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.

⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 865 PSA-graded copies:
| Outcome | Chance | Value |
|---|---|---|
| PSA 10 | 4.5% | $4,080.00 |
| PSA 9 | 30.2% | $468.00 |
| PSA 8 — typical | 33.2% | $330.00 |

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. Gem rate is estimated from cumulative PSA population, which skews toward nicer, resubmitted copies — so it overstates the true grade rate. Treat it as a guide, not a guarantee.
