To me personally it actually lowers the value. I would rather purchase an ungraded $50 set than graded because of the time it takes to crack them out (don't have the space nor desire to store tons of low value graded cards). I spent a couple hours last week releasing some 1953 Topps so I could put them in my binder and it's kind of a pain in the arse. Just keep in mind that you could have a really nice $800 card in addition to that $50 set.
