The odds

Galvantula is a Rare in Steam Siege — the pack's hit slot lands on Rare 59.7% of the time, split across 30 rare cards in the set, so pulling this exact card is roughly 1 in 50 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.

⚖️ Risk-adjusted return

Best case isn't the whole story. Weighting every grade by how often it actually happens, across 26 PSA-graded copies:

Likely outcomeChanceValue
PSA 1011.5%$43.00
PSA 942.3%$42.00
PSA ≤846.2%$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.
