Does anybody have information on the value of unopened 1975 Topps Baseball Rack Packs?

I asked around on the collectors universe forums and this is the answer I got.
For an un-opened/un-tampered rack you'd pay around $300. Anything less than $300 and you'd be getting a really good deal. Obviously it would be more if there are stars/rookies showing.
For a bbce authenticated rack, you'd pay a higher premium considering bbce authenticated it.
Hope this helps!

$300 is about right with no visible major stars.

I was wondering if Beckett Graded unopened packs that are made in 2007-08 and if so what the cost would be on that type of service?

Beckett does not grade/slab packs. I think they used to run specials where they would grade unopened packs because I remember seeing some, but not anymore.
PSA's your best bet for unopened pack grading!
