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.

The odds
Chesnaught-EX is a Commoncard — 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 9 | $14.00 | $70 | −$62 | 2.6× |
| PSA 8 | $10.52 | $70 | −$65 | 2.0× |
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. Real outcome depends on the grade achieved; PSA 10 is best-case.
Population across gradersPSA, CGC & BGS — every grade, with gem rates
Only 7% of 45 PSA-graded Chesnaught-EX copies are a gem-mint 10 (3 of 45) — the rest grade lower.
Real graded population from PSA, CGC & BGS — a lower gem rate means a Chesnaught-EX 10 is harder to pull.
