The odds
Underground Lake is a Uncommoncard — a guaranteed slot in every pack, not a rarity gamble, so there's no pull-odds figure for it.
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 | $34.72 | $70 | −$39 | 9.3× |
| PSA 9 | $24.80 | $70 | −$49 | 6.7× |
| PSA 8 | $8.00 | $70 | −$66 | 2.2× |
⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 69 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 37.7% | $35.00 |
| PSA 9 | 47.8% | $25.00 |
| PSA ≤8 | 14.5% | $4.00 |
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 38% of 69 PSA-graded Underground Lake copies are a gem-mint 10 (26 of 69) — the rest grade lower.
Real graded population from PSA, CGC & BGS — a lower gem rate means a Underground Lake 10 is harder to pull.
