Some cards have been with me since the late 90s (Charizard among them) others I have had to acquire as an adult (which has become increasingly more pricey to do). So these need to go to a new home and to fund future collecting conquests (and, oh yeah, children's college funds). Personally, I think it will go back up, esp.
If you are looking for something similar, but less expensive, I also have a complete shadowless 103/102 set listed with very good cards, just not this good.
