What this is
Sealed English booster boxes as a price cycle, 2021–2025: at release they sold at about 0.76 of list (2021–22), 0.64 (2023), 0.67 (2024) and 1.52 (2025).
How it’s built
- For each release era, take the middle release-month price as a share of US list price, from market-price charts.
- The 2023 low was 0.848 of the 2021–22 level, about 15% lower; the 2025 level was 2.36 times the 2023 low.
What we assumed
- The middle set in each era stands for the era.Some eras have only a handful of sets.
Sanity check
The series shows a full cycle: boxes fell below list and below their earlier level in 2023 before the boom lifted them. Looking only at 2025's opening level would miss the trough.
