| Target grade | Est. value | Grading fee | Net vs raw | Multiple |
|---|---|---|---|---|

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.
