Gameboy game collection advice..

I've uncovered a stack of gameboy pocket/colour/advanced games, some of them are going about 10-30 dollars on ebay but wondering if there's anything good here/ whether its worth selling seperately or a collection for a set price (some for the gameboy pocket ie Star Wars (full title) arent even listed on ebay.) Also none are 'boxed' but do work.

Pocket: Star Wars, Return of the jedi, Metroid 2: Return of Samus (seen some going for a lot)

Colour: Legend of zelda links awakening, Tony Hawks Pro Skater 2, Harry Potter Philosopher's Stone, Star wars Episode 1 Obi Wans adventures, Zelda oracle of seasons, Gameboy gallery 3, Perfect Dark (and rumble battery pack), Mario Tennis, Pokemon trading card game, Pokemon gold, blue.

Advanced: Pokemon Sapphire, Super mario World 2, Zelda Nes Classics, Harvest Moon friends of Mineral TOwn, Sword of Mana, Bomberman Tournament, Mario and Luigi superstar Saga.
