Best case isn't the whole story. Weighting every grade by how often it actually happens, across 76 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|

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.
