i should probably crack it out of the case.or will they give me a get a higher grade even if it is still in the case?
Don't bother to crack it out, just send it in "as is". If you have a minimum grade you will accept on the cross-over/regrade, state this on the submission form. The top tier graders (PCGS, NGC, ANACS and IGC) mask the grade on the holder before it goes to their graders. This is done so that the graders only judge the coin on its own merits.
If your coin does not make your minimum grade, it is returned to you in the original holder and you pay the grading costs.
P.S. - any chance you could get larger pictures of the coin? We could attribute it here for no charge.
So many coins, so little time ...
