The range is wide because these sales span different printings and conditions — 1st Edition, Shadowless and Unlimited copies all carry this card's name, and they trade at very different levels. Each sale above is labelled with what its listing claimed, so you can see which ones describe the same object. Treat the median as the typical copy, not the range.

Should you grade it?
Expected return across every likely grade, after fees — the realistic average, not the best case. Only 33.9% of copies gem (PSA 10 best case −$3); most land at PSA 9 or below.
The odds
Mystery Zone 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 | $76.11 | $71 | −$3 | 9.1× |
| PSA 9 | $16.17 | $70 | −$62 | 1.9× |
⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 56 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 33.9% | $76.00 |
| PSA 9 | 53.6% | $16.00 |
| PSA ≤8 | 12.5% | $8.00 |
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 34% of 56 PSA-graded Mystery Zone copies are a gem-mint 10 (19 of 56) — the rest grade lower.
Real graded population from PSA, CGC & BGS — a lower gem rate means a Mystery Zone 10 is harder to pull.
