⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 13 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 15.4% | $72.00 |
| PSA 9 | 61.5% | $14.00 |
| PSA ≤8 | 23.1% | $3.00 |
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.
