Pick the reading
Which Expedition Base Set cards carry the widest gap between the raw ask and the PSA 10 sold median, on 5 or more verified comps? A wide gap is where grading adds the most, and where a raw copy in gem-ready condition is priced as if it were not.

How to read it
Raw is the canonical printing's TCGplayer ask, the same figure the card page shows. PSA 10 and PSA 9 are eBay sold medians verified per listing, printed with their comp counts; a premium is only computed on 5 or more PSA 10 comps.
Gem rates come from the PSA registry snapshot and are only trusted on lines of 100 or more slabs; a zero beside a real population is a provider gap and is withheld, never shown as 0%. Moves and highs come from each product's own recorded series, trimmed at the price-rule change of 2026-09-07, and ignore cards under $5.
Every figure carries its sample. A short series, a thin comp count or a small registry is printed beside the number rather than hidden, and a card that lacks the figure a reading needs is left off that reading instead of scored on a guess.
