It is a Coin that has been Graded & sealed in a plastic box by a Numismatic (basically a grade scale) Coin Grading Service (many of them out there now & not all equal in grading practices). Hope that helps a little & Thanks for the question!
Third Tier NIC. They usually run 1 grade under NGC for MS70 & 2 under for MS69. But with subjective grading it's getting more & more difficult to tell who is really putting 110% into sticking to guidelines set forth by the NAC. Thanks for the question & sorry it took so long to answer. I've caught this nasty Flu bug & it's killing me!
