Raw $0.45 → graded PSA 8$25.99, after ~$70.25 grading fee → 57.8× the raw value.

The odds

Foongus is a Commoncard — a guaranteed slot in every pack, not a rarity gamble, so there's no pull-odds figure for it.

PSA 942.9%3 of 7

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.

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. Real outcome depends on the grade achieved; PSA 10 is best-case.

Population across gradersPSA, CGC & BGS — every grade, with gem rates

Only 29% of 7 PSA-graded Foongus copies are a gem-mint 10 (2 of 7) — the rest grade lower.
