The odds
Ninja Boy is a Uncommoncard — 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.
Population across gradersPSA, CGC & BGS — every grade, with gem rates
Only 0% of 1 PSA-graded Ninja Boy copies are a gem-mint 10 (0 of 1) — the rest grade lower.
Real graded population from PSA, CGC & BGS — a lower gem rate means a Ninja Boy 10 is harder to pull.
