I own the 150 original cards

[merfyz]

I've have these cards for like 10 years now and one day i might sell them. You guys think they'd be worth something?

Well, what do you mean by the original 150? Do you mean you have one of each of the 150 official first generation Pokemon? Or do you mean you have the entire Base Set (trainer cards and energy cards included)? That makes a huge difference in what you can expect to get for them.
