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.
