Pop-adjusted valuePSA 10 pop 7 · PSA 10 price $3,674 · float $25,715-45% vs Diamond & Pearl / Platinum curve#3 of 15 in era · slope +0.52
7 PSA 10s exist and the last PSA 10 comp was $3,674; that is 45% below what this era's population curve predicts, rank 3 of 15, in an era where population only loosely predicts PSA 10 price (slope +0.52, R² 0.16, the most-graded cards costing most).
Drawdown vs popwindow 2026-03-18 → 2026-10-29-2% from $45.24 (2026-08-08)supply 0% · flat · under the screen's 30% threshold
Observed raw near-mint $44.41 on 2026-10-19 against a window high of $45.24 on 2026-08-08: 2% below it, inside the screen's 30% threshold. PSA 10 population went 7 → 7 (0%), flat by the screen's rule, so the fall is not a supply story.
Chase concentrationDiamond & Pearl: top-3 share 34% · HHI 0.06outside the set's top 3
Outside Diamond & Pearl's top 3, which together hold 34% of a $1,083 set value over 130 cards (HHI 0.06, where 1.0 would be one card being the whole set).

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.
