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 10 | $380.00 | $74 | +$284 | 17.5× |
| PSA 9 | $40.00 | $70 | −$52 | 1.8× |
| PSA 8 | $30.00 | $70 | −$62 | 1.4× |
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.
