Slabs are BAD.A dealer or company seals an item in hard plastic, assigns a grade and value to it, and then sells this item off. Fairly often they have graded this item using their own standards, and sometimes the "Grading Company" is the same person as the "Ebay seller". You can see how this person might want to assign a VERY high grade to his items, so they might sell better.
