Is Dialga-GX worth grading?
Expected return across every likely grade, after fees — the realistic average, not the best case. Only 40.9% of copies gem (PSA 10 best case +$421); most land at PSA 9 or below.
The odds
Dialga-GX is a Secret / Rainbow in Forbidden Light — the pack's hit slot lands on Secret / Rainbow 2.5% of the time, split across 20 secret / rainbow cards in the set, so pulling this exact card is roughly 1 in 804 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 | $597.00 | $106 | +$421 | 8.5× |
| PSA 9 | $83.26 | $71 | −$58 | 1.2× |
| PSA 8 | $56.89 | $71 | −$84 | 0.8× |
⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 467 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 40.9% | $597.00 |
| PSA 9 | 39.4% | $83.00 |
| PSA ≤8 | 19.7% | $62.00 |
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 & TAG — every grade, with gem rates
Only 40% of 485 PSA-graded Dialga-GX copies are a gem-mint 10 (194 of 485) — the rest grade lower.
Real graded population from PSA, CGC, BGS & TAG — a lower gem rate means a Dialga-GX 10 is harder to pull.
