Need help on what to sell this game for.

Well, I stumbled upon a old game for the Gameboy that I used to play a lot. I never really knew why it looked different than the other gameboy games but it has a giant chip hanging out at the top and says "Two Cool Kids 6/25/92 Virgin Games". My dad told me it was a old game the developer gave him when he worked for Virgin Megastores.

I looked it up and the game is actually McKids which was released for the NES. A McDonalds game about two kids trying to help someone or something.

Anyways, I found a gameboy article on it and found out this game was never released.. So I think I have one of the very few copies ever made.

I can provide pictures, but I was curious if anyone knew how much I could sell this for? I have no need for it lol.

From what I could find:

http://cheats.gamespy.com/game-boy/mcdonald-land/

It was released in the UK, which might lower the rarity of it.

One TRILLION Dollars!

Thanks.. but I have a gameboy copy not a NES copy.
Derp.

Oh... I read McKids and instantly thought of the AVGN review for the NES game. Why not just take those pictures and post it up on ebay?
