Original XBox Demo Disc Question

[KMunley]

I have a ton of my old demo discs and I was just wondering if they were worth anything or simply trash. I don't know why, but I've held onto them for like 10 years and I'm just sick of them now.

If they are worth anything what's the best place to sell them and how much do they go for.

And if they're simply cup coasters I'd like to know as well.

Thanks ahead of time!
