What is this Microsoft CD? XP Pro x64 or Server 2003?

[Jesusfrk611]

I got a Microsoft CD with key from a trade with a bunch of other computer stuff. I need to know what the CD is (XP Pro x64, Server 2003, or both). It's labeled very weird (notice it says XP Pro x64 on top, then on the side it says Servers). I also would like to know the approximate amount (USD) I could sell it for to get money back from that trade.

umm "not for retail or OEM distribution. NOT FOR RESALE"

forget about selling it, and you would need a valid cd key, which the cd is worth nothing without it. but umm its windows xp pro x64

ooh and that is a volume license disk doesnt require activation

I feel stupid. I didn't read "Not for resale"...
I did get a key with it, read my first post. But what's up with "Servers"? Why did they put that on the disc if it's Windows XP Pro X64? Maybe I can use it if I ever get a 64 bit processor. I'm not going to upgrade to Vista anytime soon.
