Should you grade it?
Expected return across every likely grade, after fees — the realistic average, not the best case. Only 6.3% of copies gem (PSA 10 best case −$1); most land at PSA 9 or below.
The odds
Professor's Research is a Holo / V / ex in Brilliant Stars — the pack's hit slot lands on Holo / V / ex 27.9% of the time, split across 33 holo / v / ex cards in the set, so pulling this exact card is roughly 1 in 118 packs.
Estimates only. Pack odds come from CardTrack's pack model (the same one behind the pack simulator) — not an official rate. Grading odds are the real cumulative PSA population, which skews toward nicer, resubmitted copies, so it overstates the true first-submission gem rate. Full grade-by-grade breakdown below.
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 | $69.79 | $71 | −$1 | 387.7× |
| PSA 9 | $5.01 | $70 | −$65 | 27.8× |
| PSA 8 | $4.67 | $70 | −$66 | 25.9× |
⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 16 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 6.3% | $70.00 |
| PSA 9 | 50% | $5.00 |
| PSA ≤8 | 43.8% | $0.00 |
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 6% of 16 PSA-graded Professor's Research copies are a gem-mint 10 (1 of 16) — the rest grade lower.
Real graded population from PSA, CGC & BGS — a lower gem rate means a Professor's Research 10 is harder to pull.
