What this is
The search was not exhaustive ( note). The pattern is that TPC rotates the trainer per box, but it reuses a 2016-17 character (Lillie) whose 2017 cards carry the largest human premium in the record across three 2025 products.
The values
- Interval days: 973 to 385
- Distinct trainers: 3
- Repeats: 0
- Lillie span years 7 September 2017 G.E.M. to 25 April 2025 PTC: 7.63
Some detail is too fine to show here; it is kept in the trainer’s notes.
