Should you grade it?
Expected return across every likely grade, after fees — the realistic average, not the best case. Only 29.9% of copies gem (PSA 10 best case +$205); most land at PSA 9 or below.
The odds
Koffing is a Secret / Rainbow in Cosmic Eclipse — the pack's hit slot lands on Secret / Rainbow 2.5% of the time, split across 35 secret / rainbow cards in the set, so pulling this exact card is roughly 1 in 1,407 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 | $315.00 | $73 | +$205 | 8.5× |
| PSA 9 | $46.00 | $70 | −$61 | 1.2× |
| PSA 8 | $30.00 | $70 | −$77 | 0.8× |
⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 2,160 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 29.9% | $315.00 |
| PSA 9 | 51.3% | $46.00 |
| PSA ≤8 | 18.8% | $37.00 |
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 30% of 2,160 PSA-graded Koffing copies are a gem-mint 10 (646 of 2,160) — the rest grade lower.
Real graded population from PSA, CGC & BGS — a lower gem rate means a Koffing 10 is harder to pull.
