reading threads

I was reading some of the threads, and one caught my eye in particular. It was talking about NGC allowing open boxed 20th anniversary sets and the gold and silver 20th anniversary sets that were opened (not mint sealed) to be graded and designated with the black label. If this is true, there will be a marked shift in the values assigned to these coins as the population increases of these so-designated coins...and the people trying to sell mint sealed boxes won't be able to gouge the buyers as they presently do. (i.e. package of ten mint sealed box @$5500 plus!) I recently shot an e-mail off to NGC concerning this and to verify that this was true so I can send in some of my open boxed sets for grading, but have not gotten a reply as of yet. Hopefully this will be clerified officially soon.
