The range is wide because these sales span different printings and conditions — 1st Edition, Shadowless and Unlimited copies all carry this card's name, and they trade at very different levels. Each sale above is labelled with what its listing claimed, so you can see which ones describe the same object. Treat the median as the typical copy, not the range.

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 |
|---|---|---|---|---|

⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 445 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 18% | $350.00 |
| PSA 9 | 29.2% | $140.00 |
| PSA ≤8 | 52.8% | $24.00 |
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 18% of 445 CGC-graded Professor Elm's Lecture copies are a gem-mint 10 (80 of 445) — the rest grade lower.
Real graded population from PSA, CGC & BGS — a lower gem rate means a Professor Elm's Lecture 10 is harder to pull.
