The odds
Tapu Koko-GX 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 10 | $312.00 | $73 | +$237 | 145.8× |
| PSA 9 | $18.00 | $70 | −$54 | 8.4× |
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. Real outcome depends on the grade achieved; PSA 10 is best-case.
Population across gradersPSA, CGC, BGS & TAG — every grade, with gem rates
Only 21% of 129 PSA-graded Tapu Koko-GX copies are a gem-mint 10 (27 of 129) — the rest grade lower.
Real graded population from PSA, CGC, BGS & TAG — a lower gem rate means a Tapu Koko-GX 10 is harder to pull.
