>>53100072I reiterate, I think it's something important to keep in mind but there are many variables that can affect it which is perfectly illustrated in your last point. As for the cards you mentioned, I really like Dark Jolteon and was able to pull a couple of near mint 1st editions out of my ass and put the best one in my binder. For the Ho-oh I ran across one in acceptable condition for a good price. I wasn't a fan of it until I got it in person. I like it enough that I would buy one in better condition but not enough that I would be willing to pay market price for it. So it's all about how much you like a card and the kind of collection you want to have.
