I've come to understand that if a coin is considered a key date or "rare" (ex: 16-D Merc or 1877 IH), it gets a "grade bump" if slabbed by a leading TPG. How much of a bump is this exactly? Also, could someone please explain to me the logic behind this new standard? As far as I'm concerned, it's lying. A VF30 is a VF30; who cares what date/mm is on the coin? Just one more reason to buy the coin, not the slab... Help appreciated -CB
I first heard it on one of these coin boards; a member was showing how a 1877 Indian Head cent graded X (I forgot the grade/article) and a common date Indian Head cent graded X as well looked similar but obviously different in the amount of detail left. And I was reading an article recently and apparently David Hall also believes price goes into a coin's grade.
