I thought I'd start a thread for everyone to post what their Holly Grail of collectible books is. I'm going to post 2, one being the one I had if money wasn't an issue the other being a more realistic option.

The first is a 1st edition, 1st printing set of The Lord of the Rings trillogy. This is if I had all the money in the world, as that's about what it would cost me. The second is a 1st edition, 1st printing of The Sword of Shannara. This a bit more reasonable and would probably only cost me between 500 and 700 dollars.
