Signals
how these are computed →- No population read for this card yet, so it is outside the pop-adjusted and drawdown screens.
- Chase concentrationBase Set: top-3 share 58% · HHI 0.18outside the set's top 3
Outside Base Set's top 3, which together hold 58% of a $2,410 set value over 102 cards (HHI 0.18, where 1.0 would be one card being the whole set).

17 Swedish asks with a median of 26 kr ≈ $2.61 on 2026-10-29, 53% below the US near-mint market of $5.60 (2026-10-29), and 91% below the eBay sold median of $27.50 (12 sales in 90 days). Asks, not sales; 1st Edition titles excluded, both sides the unlimited print.
Terms used above
- PSA 10 pop
- The number of copies PSA has graded a 10, read by hand from public GemRate-sourced reports on a stated date.
- thin comp
- An observed PSA 10 price built on fewer than three eBay sales, or one the source flags as an outlier. It is in the fit, but it is one comp, not a market.
- slope
- b in the era's fit ln(price) = a + b · ln(pop). Negative: scarcer cards cost more. Positive: the most-graded cards cost most, so population is tracking demand rather than scarcity.
- float
- PSA 10 price × PSA 10 population: the market value of every PSA 10 of the card in existence. A small float is a thin market in both directions.
- HHI
- Herfindahl–Hirschman index: the sum of every card's squared share of the set's value, from near 0 (value spread evenly) to 1.0 (one card is the whole set).
- spread
- Tradera median in dollars ÷ US market − 1. Negative means the Swedish asks sit below the US near-mint market, before postage, VAT and duty, none of which is subtracted.
- asks, not sales
- Tradera figures are live asking prices (plus bids on auctions closing within a day), not completed sales. An ask nobody meets is not a price, and asks run above what sells.
