Some modern sets are two sets wearing one name: a main checklist nobody prices, and a small annex that holds nearly all the money. We measured all eight subset and parent pairs in the catalog. In Crown Zenith the Galarian Gallery is 30.4% of the cards and 90.18% of the value, and its median card is $13.16 against $0.20 in the main set.

| Crown Zenith Galarian Gallery | 70 | $13.16 | Crown Zenith | $0.20 | 30.4% | 90.18% |
| Shining Fates Shiny Vault | 122 | $2.65 | Shining Fates | $0.24 | 62.6% | 88.72% |

Two formats, opposite behaviour
The table sorts into two groups and they are not the same product. In the four Trainer Gallery sets the single most valuable card is always in the MAIN set. Giratina V at $822.95 beats Lost Origin's best gallery card Pikachu V at $125.92. Lugia V at $524.94 beats Rayquaza VMAX at $202.18. Charizard V at $297.13 beats Umbreon VMAX at $111.43. The fourth pair is the same shape: Astral Radiance's Machamp V beats its gallery's Starmie V.
In the Vault and Gallery led sets it reverses completely. Charizard GX in the Hidden Fates Shiny Vault is $761.96 against Hidden Fates' best main set card Jessie and James at $73.36. Giratina VSTAR at $314.90 against Crown Zenith's Pikachu at $49.36.
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.
