Should you grade it?
Expected return across every likely grade, after fees — the realistic average, not the best case. Only 28.4% of copies gem (PSA 10 best case +$55); most land at PSA 9 or below.
The odds
Koffing 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 | $127.50 | $71 | +$55 | 132.8× |
| PSA 9 | $36.03 | $70 | −$35 | 37.5× |
| PSA 8 | $27.37 | $70 | −$44 | 28.5× |
⚖️ Risk-adjusted return
Best case isn't the whole story. Weighting every grade by how often it actually happens, across 1,378 PSA-graded copies:
| Likely outcome | Chance | Value |
|---|---|---|
| PSA 10 | 28.4% | $128.00 |
| PSA 9 | 43.2% | $36.00 |
| PSA ≤8 | 28.4% | $1.00 |
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 28% of 1,378 PSA-graded Koffing copies are a gem-mint 10 (391 of 1,378) — the rest grade lower.
Real graded population from PSA, CGC & BGS — a lower gem rate means a Koffing 10 is harder to pull.
