Yep!  You never know.  Example; I have a copy of Pink Floyd's Dark Side of the Moon with the labels reversed. I have been told that those are already worth a few bucks and then a Crosby Stills and Nash album,,,I can't remember what the deal was on it cause it has been so long since I looked at it but, it is a collectors item already.  Soon they will be just like the METAL lunch pales we used to use when we were kids.  I used to have a Scooby Doo and a Superman lunch pale that I saw go for over $1000 on one of the TV shows on the History Channel!  Amazing!
