Trend started big time in the comics world.CGC has been slabbing comics for at least ten years. They sold like hotcakes for a bit too. Now, people seem to have come to their senses as they aren't selling anywhere near as good as they used to. I guess people decided they wanted to read the comics and realized that once it's slabbed, it's pretty much a done deal, especially after spending all of that money. There is wisdom here somewhere.
