I have a few questions on the application of the Sheldon Grading Scale that he whom has experience with the professional grading services may be most helpful.
First: How does a grader reconsile a grading such as: "MS66 BN" ........ ( i.e.,"having nearly full luster" and "BN" seem contradictory.)
and secondly: what type of evaluation process/equipment (?) is used by examiners to determine "absolutely no trace of wear" with reference to the coin in the attached images?
