What is this N64 collection worth?

I'm looking into buying this N64 collection but I'm unsure of many values. I'm honestly not sure who to ask, but I figure this is a good place to start

N64 black console

3 controllers

Yoshi's Story

GoldenEye 007

Mario Kart 64

Donkey Kong 64

Diddy Kong Racing

Ogre Battle 64

Rush 2

Aidyn Chronicles

Top Gear Rally

Mystical Ninja

Cruisin' USA

Wave Racer

I'd really appreciate if somebody could help me out, I'd like to know what I should offer for this collection. Thanks in advance!

edit: well, it's not really a collection, but with lack of a better word that is what I chose.

@thecourier:Assuming that the unit and controllers are in working condition, clean, have all of the pieces/covers/cords/cables, and are in decent aesthetic condition, and the games (cartridges only) are clean, work without issue, stickers are in tact and not faded...

You're looking at about $325.

If the unit, controllers, or games, come with boxes, inserts, and/or manuals, it would be worth quite a bit more. On the other hand, if they aren't in at least the condition described above, then it would be worth less. It's hard to say exactly without knowing the condition of each item. It should also be noted that this estimate is based on the individual items themselves. Point being...if I were selling this package, I wouldn't necessarily expect to get $325 for it. So to answer your question (again, assuming condition here,) I'd try offering $250. Hope this helps.

@itstotallymike: Thanks, that sounds about right. I'll probably offer something close to that. Console seems to be in good condition, but I'll make sure to check everything (and play it) before I buy it.

Anyone else? I'd like to have another opinion just to make sure.

@itstotallymike: Ended up buying it for 250, and they even threw in an extra controller. How did I do?

Nice haul man! Enjoy.

Hopefully u have the expansion Pak and controller Pak. Controller Pak needed to keep unlocked cars in crusin USA. Expansion needed for donkey Kong
