{"asOf":"2026-09-20","hitValue":{"version":"hitsignal-v1:trimmed-mean/last10-6mo/decay14d/trim15","summary":"A card's value is read per printing and per condition or grade, never averaged across them. Where a source gives us raw sales, we take the last 10 within 6 months, drop the top and bottom 15%, and weight recent sales more (a sale two weeks old counts half). Where a source gives us a computed price, we take that number as theirs and add confidence, provenance and segmentation.","segments":["graded vs raw","each grade separately","market (US only at launch)","sale vs ask — asks are shown live and never enter the value","auction vs fixed price"],"confidence":[{"score":5,"meaning":"a sale within the last two weeks, adequate sample, tight spread"},{"score":4,"meaning":"recent sales, reasonable sample"},{"score":3,"meaning":"sales within the window, thin sample or wide spread"},{"score":2,"meaning":"stale or very thin — a point estimate is becoming dishonest"},{"score":1,"meaning":"a comparable-based estimate or a single old sale: we show a range, not a number"}],"provenance":"Every stored value carries its source, licence, basis (sale or estimate), sample size, as-of time and this version string.","sources":["completed sales from major marketplaces (sports) — our estimator runs on the raw sales","per-condition market prices (trading card games)","auction results (sports; short-term cache only)"],"history":"Our series begins the day we started collecting for a card; no backfill exists. Movers and one-year ranges come from the source's own statistics from day one."},"rollups":{"summary":"A binder or a shelf is the sum of its copies at their own condition and grade. A copy counts once per shelf however many binders hold it. Confidence is not averaged: we show how much of the value comes from high-confidence estimates.","snapshot":"shelf-snapshot-v1"},"costBasis":{"summary":"Cost basis and profit come only from acquisition prices you entered. We say how many of your cards are costed."},"legend":{"version":"legend-v1","summary":"Your Legend is one card, not simply the priciest: value (45%), scarcity (25% — serial numbering, print run, rarity tier, a gem grade) and significance (30% — the oldest card you own if it is at least 15 years old, the one you have held longest if over three years, a high-confidence value). It changes only on a genuine change."},"completion":{"summary":"A set or run is a rule over the catalogue. Progress counts distinct printings (master), distinct cards (base — any printing counts) or an explicit list. The weighted score gives each card a weight of 1–10 by its value rank among the set; raw cards count exactly like graded ones. Cost to complete is the sum of the missing cards' near-mint values and is withheld while any missing card is unpriced."},"rarity":{"version":"rarity-tiers-v1","summary":"Native rarity labels are kept as printed and also mapped to one coarse cross-game scale: common, uncommon, rare, ultra rare, secret rare, unknown."},"identification":{"summary":"Cards are identified from your photograph: a detector finds each card, a vision model reads what is printed on it, and a catalogue lookup or a specialist identification service settles the exact card. Anything below our confidence bar goes to your review queue — a wrong card is never filed silently. Rows we build ourselves come only from facts printed on your card."},"limits":["No price history before the day we started collecting for a card.","One market (US) at launch.","Population data is not yet an input.","Sealed product is not yet valued."]}
