The odds
Forest Seal Stone is a Holo / V / ex in Silver Tempest — the pack's hit slot lands on Holo / V / ex 27.9% of the time, split across 30 holo / v / ex cards in the set, so pulling this exact card is roughly 1 in 108 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 | $13.00 | $70 | −$57 | 39.4× |
| PSA 9 | $7.21 | $70 | −$63 | 21.8× |
⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 426 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 22.5% | $13.00 |
| PSA 9 | 31% | $7.00 |
| PSA ≤8 | 46.5% | $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

Real graded population from PSA, CGC & BGS — a lower gem rate means a Forest Seal Stone 10 is harder to pull.
