The headline is the built-in estimator's number: no live marketplace read carries weight for this condition yet. Rows marked modelled are that estimator, not a marketplace read; the first live read replaces them in the headline. Observed rows marked not blended are regional asks or mixed-condition sales, shown but never averaged into the US near-mint figure.
Signals
how these are computed →- No population read for this card yet, so it is outside the pop-adjusted and drawdown screens.
- Chase concentrationBW Black Star Promos: top-3 share 100% · HHI 0.5436% of set value#2 card in the set
BW Black Star Promos's cards sum to $108 over 101 cards; this card is 36% of that as its #2 card, and the top 3 together hold 100% (HHI 0.54, where 1.0 would be one card being the whole set). The set is not ranked yet: 0 of 101 cards have an observed price.
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.
