Hi and welcome. It really is up to you I'f you will like to keep them open or sealed. Some people keep them sealed for resale value, some open to be able to display them, and some buy two to keep one sealed and the othe to display. So really it all depends on you and what you are interested in. Honestly I have always kept all my stuff sealed and if I was able to obtain another copy later on for a lot less then I will open that one. But now when I think of it I would of just kept the really rare ones sealed and the ones that are over produced open, but now recently I started selling my whole collection and I regret now not opening them to be able to look at the extra contents.
