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.

From 44 completed sales recorded between Apr 6, 2026 and Aug 13, 2026. Sold prices only — asking prices are never counted. The range is wide because these sales span different printings and conditions — 1st Edition, Shadowless and Unlimited copies all carry this card's name, and they trade at very different levels. Each sale above is labelled with what its listing claimed, so you can see which ones describe the same object. Treat the median as the typical copy, not the range.

Is Gastrodon West Sea worth grading?
Expected return across every likely grade, after fees — the realistic average, not the best case. Only 4% of copies gem (PSA 10 best case +$126); most land at PSA 9 or below.
The odds
Gastrodon West Sea is a Holo / V / ex in Secret Wonders — the pack's hit slot lands on Holo / V / ex 33% of the time, split across 22 holo / v / ex cards in the set, so pulling this exact card is roughly 1 in 67 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.
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 10 | $209.55 | $72 | +$126 | 17.9× |
| PSA 9 | $90.00 | $71 | +$7 | 7.7× |
| PSA 8 | $50.00 | $70 | −$32 | 4.3× |
⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 126 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 4% | $210.00 |
| PSA 9 | 34.1% | $90.00 |
| PSA ≤8 | 61.9% | $34.00 |
Net = graded value − raw value − grading cost (tier fee + ~$20 round-trip shipping), using PSA fees as of 2026-06-28; 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.
Population across gradersPSA, CGC, BGS & TAG — every grade, with gem rates
Only 4% of 128 PSA-graded Gastrodon West Sea copies are a gem-mint 10 (5 of 128) — the rest grade lower.
Real graded population from PSA, CGC, BGS & TAG — a lower gem rate means a Gastrodon West Sea 10 is harder to pull.
