Should you grade it?
Expected return across every likely grade, after fees — the realistic average, not the best case. Only 32.3% of copies gem (PSA 10 best case −$21); most land at PSA 9 or below.
The odds
Cornerstone Mask Ogerpon ex is a Holo / V / ex in Prismatic Evolutions — the pack's hit slot lands on Holo / V / ex 27.9% of the time, split across 25 holo / v / ex cards in the set, so pulling this exact card is roughly 1 in 90 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 | $50.00 | $70 | −$21 | 53.2× |
| PSA 9 | $14.00 | $70 | −$57 | 14.9× |
⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 93 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 32.3% | $50.00 |
| PSA 9 | 54.8% | $14.00 |
| PSA ≤8 | 12.9% | $1.00 |
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
