Message:: [QUOTE="V. Kurt Bellman, post: 2677610, member: 71723"]I learned in Orlando many things about TPG's.1) Unless the MATERIAL ITSELF identifies the submitter, graders NEVER know. All this "it depends who you are" garbage is pure hokum.2) Both NGC and PCGS use the two graders and a finalizer system. On high end material, at NGC, Mark Salzburg or Rick Montgomery are THEMSELVES the finalizers.3) At PCGS, the second grader is blind to the first grader's grade, but the finalizer sees both. At NGC, the second grader sees the first grader's grade and the finalizer sees both.4) 80% or more of the grade is determined with NO magnification.  Swirling the coin under a single incandescent lamp is central to determining grade.5) Magnification is mostly used to determine what the "something" is that caused a luster break during  the swirl.6) Graders, especially graders of modern coins, are supposed to handle 3,600 coins per day. Do the math. 8 seconds per coin.[/QUOTE]
