Even truer for books.

I moved fairly recently and disposed of my record collection and actually got good money for them because they are currently very hot items. Ten years ago no one would have wanted them.

Good luck. It's sad to get rid of a collection like that, but there's some satisfaction if you know they are going to someone who will appreciate them as much as you do.
