Message:: [QUOTE="Lehigh96, post: 2016560, member: 15309"]I think I would characterize the decision to allow for roll friction a "conscious" one but when I hear loosening of standards I think of a change to the standards for numerical grades.  Allowing for roll friction is more of an expansion of market grading principles and not what I would call loosening of standards.  I think I will make my next example one where roll friction is involved. I thought your answer was going to be more abstract.  I think it is safe to assume that most knowledgeable numismatists understand that there is often a fine line between high end (PQ) coins of one grade and low end coins of the next highest grade.  And when the price jump between grades is significant, it provides financial incentive for people to resubmit their PQ coins until the inherent subjectivity of coin grading yields a higher grade.  This is what I consider the quintessential example of gradeflation.  However, over time, is it possible that the sheer number of low end coins for a particular grade could desensitize the market into believing that these low end coins are actually representative of what that grade should look like rather than low end for the grade?  If that were to happen, then there really would be an unconscious movement of the grading standard.[/QUOTE]
