>>54017299most of my cards are from opening packs ever since I was a kid. I only collect pokemon, I don't sell them even if I get a double of a nice card, unless I get a nice trainer card that's worth more than a few bucks then I sell it for whatever at my lgs or give it to friends. If I buy singles its troll n toad, tcgplayer, and ebay. collectorscache and regular retail joints for sealed stuff. I use pokedata which is decent for keeping track of collections and prices. I'd say I'm not the best to ask for advice on potential market trends, I just collect and consoom due to heavy nostalgia. I have most of the english video games too, just missing some gamecube and wii era stuff.
