Star Wars Racer Demo Cartridge

Mar 2012
So I won an auction a couple days ago for a used Nintendo 64 and it came with 5 games. One of those games, in the picture was Star Wars Racer. I couldn't tell from the picture, but when I opened the box today and went through the games, I noticed that the Star Wars Racer was actually a demo. It says Not For Resale on the front of it and when I power on the N64 with it in, it is actually a demo cartridge.

I know I saw one of these fetch about $350 on eBay recently. That game of course was The Legend of Zelda: Majoras Mask but I wonder if this one is worth anything.

I have no intention of selling it as I am a collector of things like this but i would assume it would be worth something as the list of N64 demo cartridges isn't extensive and I don't know how many of these are still around.
