    "Population: English priced cards grouped by the set name the catalog records, covering the eight subset and parent pairs present. Prices resolve through the shared canonical printing rule as of September 3, 2026. Subsets are separate set rows in the catalog, so parent totals exclude their subset by construction and nothing is double counted. Totals are a one day cross section, not returns, and no time series claim is made. Median is the median priced card in that set row. No regression is run. RECHECKED 2026-09-22: prices are a current-state store with no history, so September 3 cannot be replayed, but every figure rebuilds within drift today. Card shares return 57.67%, 30.43%, 62.56%, 51.02%, 13.49%, 12.24%, 12.15% and 10.87% against the eight printed here, and value shares 92.23%, 90.29%, 89.05%, 81.70%, 46.43%, 33.55%, 29.76% and 23.93% against 92.14%, 90.18%, 88.72%, 83.01%, 46.58%, 33.75%, 30.27% and 24.25%. The rule that the main set holds the dearest card holds in all four Trainer Gallery pairs, including Astral Radiance, where Machamp V reads $195.66 against Starmie V at $120.23. One thing has changed since publication: the catalog now holds a ninth pair, the 30th Classic Collection inside 30th Celebration, which released on September 16 and did not exist when the eight were counted."
