The odds
The Rocket's Training Gym is a Rare in Gym Heroes — the pack's hit slot lands on Rare 67% of the time, split across 23 rare cards in the set, so pulling this exact card is roughly 1 in 34 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 9 | $29.25 | $70 | −$54 | 2.3× |
| PSA 8 | $11.19 | $70 | −$72 | 0.9× |
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 14% of 64 PSA-graded The Rocket's Training Gym copies are a gem-mint 10 (9 of 64) — the rest grade lower.
Real graded population from PSA, CGC, BGS & TAG — a lower gem rate means a The Rocket's Training Gym 10 is harder to pull.
