 "methodology": {
  "marketPrice": "A price is a price of a card IN A STATED CONDITION ON A STATED DAY. `marketPrice` is therefore one thing only: a TCGplayer NEAR MINT condition quote for this exact printing, in USD, whose `asOf` is the day the provider OBSERVED it, and it is published only while that observation is less than 30 days old, because the boards compare a seven-day window against the seven before it and a reading older than a month cannot sit inside either side. A played quote (lightly, moderately or heavily played, or damaged) is NEVER published as this card's price at any age: the daily export carries one condition-less number per product that the provider builds by falling back down the card's condition ladder, so treating it as Near Mint published a Moderately Played quote from 23 September as a near mint price dated today on CoroCoro Mew, and the same shape on 1,563 products. When no publishable Near Mint quote exists, `marketPrice` is null and `priceWithheld` states what we do hold. moonstone sells no cards and quotes no ask of its own.",
  "priceWithheld": "Present exactly when `marketPrice` is null and we hold a figure or a quote worth stating, because a refusal must not look like an empty result. `recordedFigure` is the daily export's number with `condition: null`, which is the literal truth that nothing states what condition it describes, dated to the day WE recorded it (`asOfKind: \"recorded\"`). `heldQuote` is a labelled condition quote with the day the provider observed it: it answers what a copy in that condition is worth, which is a real question, and it is never this card's price. `reason` says which rule withheld the price: `is-a-played-quote` (the figure equals one of this card's own played quotes to the cent), `stale-near-mint`, `no-near-mint-quote`, `ladder-is-another-printing` or `ladder-not-one-market`.",
  "gradedMedians": "Medians of verified sold listings for that grade, never a multiplier applied to the raw price. Every figure carries the number of sales behind it, and a price is published only when that sample reaches 10 recorded sales. `reason` says which rule withheld a grade, and one of them is not about the count: `diverges` means the sample DID reach the bar and the figure was refused anyway, because our newest reading of that grade and our long-run median are more than 50% apart, so neither is published as the price and `facts` and `questions` name both readings with their own sample sizes. A grade with fewer sales than the bar is listed with `quotable: false`, its recorded sale count and no price: measured against an independent source, medians standing on fewer than 10 sales deviated 30.7% on average against 8.4% for those standing on 20 or more. A single sale is never published as a price at any sample size. THE POPULATION OF EACH COUNT: `sales` is the sample behind `price`, or behind the figure we withheld, and `recordedSales` is every sale we hold recorded for that grade whether it cleared the bar or not, so the two differ wherever a price was withheld or our long window published because the trailing window was too thin to quote. Graded comps are pooled by TCGplayer product, so where `printing.shared` is true every count here covers each printing that product carries.",
  "population": "A snapshot of the PSA registry for this card. A gem rate is reported only when the registry row breaks out the tens; an absent breakdown is reported as absent, never as zero.",
  "priceSeries": "moonstone's own daily price tape, one reading per day. `points` is how many days we hold, not how many days the card has existed."
