Signals
how these are computed →- Pop-adjusted valuePSA 10 pop 73 · PSA 10 price $7,319 · float $534,305-16% vs Wizards of the Coast (Vintage) curve#14 of 33 in era · slope -0.16
73 PSA 10s exist and the last PSA 10 comp was $7,319; that is 16% below what this era's population curve predicts, rank 14 of 33, in an era where population barely predicts PSA 10 price (slope -0.16, R² 0.04, scarcer cards costing more).
- Drawdown vs popwindow 2026-03-18 → 2026-10-290% from $276 (2026-10-17)supply 0% · flat · under the screen's 30% threshold
Observed raw near-mint $276 on 2026-10-17 against a window high of $276 on 2026-10-17: level with it, inside the screen's 30% threshold. PSA 10 population went 73 → 73 (0%), flat by the screen's rule, so the fall is not a supply story.
- Chase concentrationGym Challenge: top-3 share 33% · HHI 0.069% of set value#2 card in the set
Gym Challenge's cards sum to $3,124 over 132 cards; this card is 9% of that as its #2 card, and the top 3 together hold 33% (HHI 0.06, where 1.0 would be one card being the whole set).

2 Swedish asks with a median of 1,855 kr ≈ $187 on 2026-10-25, 32% below the US near-mint market of $276 (2026-10-17), and 40% below the eBay sold median of $313 (24 sales in 90 days). Asks, not sales; under three asks, so the screen shows it unranked; 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.
