Anecdotal evidence suggests that CAC is more strict stickering competitors coins than they are with coins submitted to be holdered in a CACG slab. Walking the bourse floor at a couple shows has revealed more than a few coins in CACG holders that would never qualify for a sticker in a PCGS or NGC holder simply because the coin is plain ugly. With all due respect to technical grading, no one likes an ugly coin, and few will pay a premium for one unless it is way up on the rarity scale.
