    "Set-value series from the moonstone set tracker, the stored weekly series for Scarlet & Violet 151, which opens on 2025-01-27 and whose last reading before publication is 2026-07-21; it records a set value without a constituent count, so a step in it cannot be tested for a basket change the way the set pages test their own 30 and 90 day figures. Gem rates from daily PSA registry snapshots: lifetime is the earliest snapshot we hold for the card, 2026-08-08, and the recent window is the 329 slabs added by 2026-08-20. Both through August 28, 2026. Not financial advice."
