World Championships No. 1/2/3 Trainers


How much are the No. 1/2/3 Trainers from the World Championships worth? I remember the 1st No. 1 Trainer on ebay (from 2005 Worlds) sold for $7500… but nowadays they are not worth as much I suppose…
I would be happy for estimated values for ungraded as well as graded cards.

Thanks in advance
