The top chase of Gym Challenge 1st Edition is Blaine’s Charizard which has had multiple confirmed sales from the ~$6.5k range in May up to $13.7k earlier this
month.
For this booster box, there were multiple sales in 2024 around $13k and a couple of sales this year that show somewhat of a trendline of big upward growth (somewhat because the sales are very limited for boxes at this price). There was one
sale in October of this year with a winning bid of $16k.
