Should you grade it?
Expected return across every likely grade, after fees — the realistic average, not the best case. Only 52.8% of copies gem (PSA 10 best case +$58); most land at PSA 9 or below.
The odds
Kingdra-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 | $145.96 | $71 | +$58 | 9.0× |
| PSA 9 | $35.00 | $70 | −$52 | 2.1× |
| PSA 8 | $13.00 | $70 | −$73 | 0.8× |
⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 691 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 52.8% | $146.00 |
| PSA 9 | 34.9% | $35.00 |
| PSA ≤8 | 12.3% | $16.00 |
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 53% of 691 PSA-graded Kingdra-GX copies are a gem-mint 10 (365 of 691) — the rest grade lower.
Real graded population from PSA, CGC & BGS — a lower gem rate means a Kingdra-GX 10 is harder to pull.
