Should you grade it?
Expected return across every likely grade, after fees — the realistic average, not the best case. Only 49.1% of copies gem (PSA 10 best case −$41); most land at PSA 9 or below.
The odds
Professor's Research is a Secret / Rainbow in Pokémon GO — the pack's hit slot lands on Secret / Rainbow 2.5% of the time, split across 12 secret / rainbow cards in the set, so pulling this exact card is roughly 1 in 482 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 | $38.17 | $70 | −$41 | 4.2× |
| PSA 9 | $17.50 | $70 | −$62 | 1.9× |
⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 481 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 49.1% | $38.00 |
| PSA 9 | 33.7% | $18.00 |
| PSA ≤8 | 17.3% | $9.00 |
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 49% of 481 PSA-graded Professor's Research copies are a gem-mint 10 (236 of 481) — 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.
