N64

[Chaels Arms]

out of the box range from $1 to $1000 depending on game and condition.
Price charting is a good source:

This is the most expensive N64 has ever been.

Awesome, thank you. I actually think I have a few still in opened boxes (Ocarina of Time and Banjo-Kazooie). I always thought these things needed to be unopened and perfectly preserved to be worth anything.

Just depends on the market for the game. You'd obviously get top dollar if you have everything with the box but just the cart by itself is still good to some collectors.
