Professional "slab" grading is for preservation and resale, that's about it. Grading runs $6 to $12 per card, so take that into consideration. On the modern stuff (80's and newer), I might grade limited edition, low population cards and maybe autographed cards. Possibly rookie cards of potential HOF'ers.
Pick out your best condition cards that fit the above categories and send 10 or 20 in and see how you do. Word of warning: you may be disappointed the the graders aren't as fond of your cards as you are. That's part of the learning process.
Finally, let us all know how you did. We'll rejoice or cry right along with you. Really.
