Robimo, "grading" a card is fairly easy. its just the condition the card is in. all of them can do it well, but some are more consistent than others.
SGC - 9 (tough graders, miss very little IMO)
PSA - 6 (occasionally overgrade, IMO)
GAI - 5 (inconsistent)
BVG - 7 (before going to BVG, Beckett did well at grading vintage cards and were tough - I'd give them a 9 - but they are much more lenient with their more recent BVG system and sometimes inconsistent)
some side notes:
1) the above is just "grading". determining authenticity is a different subject. i'd put the most trust in SGC, then BVG, then PSA, then GAI.
2) slab LOOKS, i'd rate them SGC by a long shot, then PSA, then GAI and BVG
3) slab protection, i like BVG the best. you don't have to worry if your beckett slab has been tampered with, cuz the thing is bulletproof. Though I've never tried tampering with a slab, the general consensus seems to be PSA is next-toughest, and SGC is pretty easy to get into. no idea about GAI.
