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.

Holo / V / ex33%32 cards

PSA 933%224 of 679
PSA graded so far679
Gem Mint 1083
Total graded679

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 679 PSA-graded copies:

Likely outcomeChanceValue
PSA 1012.2%$3,300.00
PSA 933%$656.00
PSA ≤854.8%$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.
