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.

PSA 939.6%55 of 139
PSA graded so far139
Gem Mint 1049
Total graded139

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.

⚖️ Risk-adjusted return

Best case isn't the whole story. Weighting every grade by how often it actually happens, across 139 PSA-graded copies:

Likely outcomeChanceValue
PSA 1035.3%$140.00
PSA 939.6%$53.00
PSA ≤825.2%$5.00

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 35% of 139 PSA-graded Koffing copies are a gem-mint 10 (49 of 139) — the rest grade lower.

What NM / LP / MP actually mean — and how much they cost

For context: a graded PSA 6 slab of this card sells for about $8 (cert-verified) — a heavily-played raw copy shouldn't cost much more than that.
