How much is all of this stuff worth?

[Goldie]

I'm thinking of selling all of these old systems and games altogether on craigslist or something, but I can't think of a good price for all of it. Here's a couple pictures of everything, can you give me your ideas or opinions? This isn't an advertisment I just don't want to end up selling it for way too cheap or too high.
There's an original Gameboy, three Gameboy Pockets, a Gameboy Color, Megaman Xtreme 2, Metroid II, Snoopy's Magic Show, Yugioh Dark Duel Stories, Dragon Warriors Monsters 2 Cobi's Journey, Robopon Sun Version, and Turok 2 Seeds of Evil.
Thanks for all your price suggestions.

I'd personally recommend checking out what other people are selling them for, on eBay or something. I did that when I had a load of VIC-20 tapes to sell.

A lot of games like that should get you something. Ebay is the best choice for that. Start the bid as low possible, and set the time for a 5-7 days. Not sure how much it'll get you, but it's the easiest way to attract buyers.
