  "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."
