2 Swedish asks with a median of 250 kr ≈ $25.14 on 2026-10-25, 235% above the US near-mint market of $7.50 (2026-10-24), and 73% above the eBay sold median of $14.50 (9 sales in 90 days). Asks, not sales; under three asks, so the screen shows it unranked.

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.
