How much could i sell my pokemon games for?

i have a few Pokemon games from a long time that i haven't played in years. i have Pokemon yello, blue, crystal, and red for game boy color. i don't have the original box and the cartridges are in great condition.|||Actually, these games are no longer being made and you can't get them in most highstreet stores. Red, Blue, Yellow and Crystal you probably sell for 拢7 each, but keep them for a bit longer and they will soar up in price in a couple of years.|||Well....not much, I would say. Since the Nintendo DS came out, older Gameboy Color games have dropped in value, especially Pokemon. I could go out to EB Games, and buy a used Pokemon : Red version for about $3.|||Not many game stores take them. Gamestop won't. If you have a playtrade you could get $15 for all of them. You could sell them online but there are hundred of them, you need to have a competetive price.|||I wouldn't think you'd get that much. Not really cause they aren't good, but anyone can download these games now, PLUS there are remakes so not many people would want to buy them.
