Ngc's Verbal Coin Grading Scale

All,

As you know, my grading skills are lacking. Prior to my tapping you experienced collectors for specific grading estimates, I was using primarily PCGS's photo guide and NGCs verbal descriptions, the latter more for MS-level grading. I have also used some videos I found online for assistance and comparing some of my coins to the graded coins on ebay, Great Collections, and Heritage, where I see flaws that would seem to have been ignored or at least minimized from the PCGS/NGC sites. I am particularly interested in getting some perspectives about the accuracy of NGC's descriptions of MS grading characteristics. I recognize that grading is a blend of objectivity and subjectivity (science/art) and that it is difficult to capture things like "eye-appeal" and "luster", the length and depth of scratches, etc. I know that it is certainly more difficult to be accurate by looking at photos rather than the actual coin(s) Perhaps the easiest explanation is my inexperienced "eye" for the features. Any comments would be welcome.

Thanks a lot!

Bill
