Which Base Set 2 cards carry the widest gap between the raw asking price and the PSA 10 sold median, on 10 or more verified sales? 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.
PSA 10 verified sold median over the raw NEAR MINT ask, cards with 10 or more verified PSA 10 comps whose raw figure is a Near Mint quote.
No Base Set 2 card has the recorded figures this reading needs. That says something about our records, not about the set: the other readings may still hold rows.
Raw is the main printing's TCGplayer asking price, the same figure the card page shows. PSA 10 and PSA 9 are eBay sold medians verified per listing, shown with how many sales they rest on; a premium is only computed on 10 or more PSA 10 sales.
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 September 7, 2026, and ignore cards under $5.
Every figure carries its sample. A short series, a small number of sales or a small PSA population 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.
