Should you grade it?
Expected return across every likely grade, after fees — the realistic average, not the best case. Only 0.3% of copies gem (PSA 10 best case +$858); most land at PSA 9 or below.
The odds
Dialga 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 10 | $972.00 | $90 | +$858 | 40.7× |
| PSA 9 | $780.00 | $88 | +$668 | 32.7× |

⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 930 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 0.3% | $972.00 |
| PSA 9 | 11.1% | $780.00 |
| PSA ≤8 | 88.6% | $24.00 |
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 0% of 930 PSA-graded Dialga copies are a gem-mint 10 (3 of 930) — the rest grade lower.
Real graded population from PSA, CGC & BGS — a lower gem rate means a Dialga 10 is harder to pull.
