The odds

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

PSA 10 (gem mint)29.9%376 of 1,256
PSA 939.9%501 of 1,256
PSA graded so far1,256
Gem Mint 10376
Total graded1,256

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 1,256 PSA-graded copies:

Likely outcomeChanceValue
PSA 1029.9%$90.00
PSA 939.9%$45.00
PSA ≤830.2%$0.00

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.
