Do you have anything rare in your collection? Something that will be worth a lot as time goes on?

In terms of regular open games that sell for a lot on eBay, I've got a really nice copy of Fire Emblem: Path of Radiance for the Gamecube. I got it when it was new. I loved playing it but haven't gone back to it that much so I haven't really had a reason to mess with the case or make it look used. Recent completed eBay listings have it going for upwards of 250 dollars.

As far as memorabilia goes, I have a sealed The Legend of Dragoon promotional VHS tape. It still has the shipping information of the previous owner, mailed to them by Game Pro magazine. I've seen it go for about 40 opened, but sealed I have no idea.
