The odds
Mr. Stone's Project is a Uncommoncard — 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

| PSA 10 | $49.00 | $70 | −$22 | 51.6× |
⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 86 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 48.8% | $49.00 |
| PSA 9 | 23.3% | $20.00 |
| PSA ≤8 | 27.9% | $1.00 |
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 71% of 7 PSA-graded Mr. Stone's Project copies are a gem-mint 10 (5 of 7) — the rest grade lower.
Real graded population from PSA, CGC & BGS — a lower gem rate means a Mr. Stone's Project 10 is harder to pull.
