The odds
Island Cave 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 | $75.58 | $71 | +$4 | 57.7× |
| PSA 9 | $26.00 | $70 | −$46 | 19.8× |
| PSA 8 | $6.00 | $70 | −$65 | 4.6× |
⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 128 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 18.8% | $76.00 |
| PSA 9 | 28.1% | $26.00 |
| PSA ≤8 | 53.1% | $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.
