Should you grade it?
Expected return across every likely grade, after fees — the realistic average, not the best case. Only 12.2% of copies gem (PSA 10 best case +$2,842); most land at PSA 9 or below.
The odds
Nidoking is a Holo / V / ex in Aquapolis — 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.
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 | $3,300.00 | $228 | +$2,842 | 14.3× |
| PSA 9 | $656.00 | $87 | +$339 | 2.9× |
| PSA 8.5 | $342.00 | $73 | +$39 | 1.5× |
| PSA 8 | $299.99 | $73 | −$3 | 1.3× |
⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 679 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 12.2% | $3,300.00 |
| PSA 9 | 33% | $656.00 |
| PSA ≤8 | 54.8% | $230.00 |
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 — every grade, with gem rates
Only 12% of 679 PSA-graded Nidoking copies are a gem-mint 10 (83 of 679) — the rest grade lower.
Real graded population from PSA, CGC & BGS — a lower gem rate means a Nidoking 10 is harder to pull.
