I've started going through old gaming stuff to find things I'm willing to part with, and stumbled upon these.

Soulcalibur II kiosk demo discs for Xbox, Gamecube and PlayStation 2. The Xbox one is sealed in the cardboard sleeve. The others include their sleeve, but have been opened. I can't decide if I want to sell them off or not, and can't seem to find any price point that might help make up my mind.

The lack of information -- coupled with them being kiosk demos -- makes me suspect they might be worth something, but you never really know with these sorta things. Anyone have any clue what I might be able to fetch by posting them on eBay, or for sale here or elsewhere?

Thanks for the help!
