Grade-by-grade ROI & risk-adjusted outcomesNet vs raw per target grade, plus the probability-weighted distribution

⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 65 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 30.8% | $89.00 |
| PSA 9 | 30.8% | $11.00 |
| PSA ≤8 | 38.5% | $7.00 |
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 31% of 65 CGC-graded Mystery Plate β copies are a gem-mint 10 (20 of 65) — the rest grade lower.
Real graded population from PSA, CGC & BGS — a lower gem rate means a Mystery Plate β 10 is harder to pull.
