<p>[QUOTE="brg5658, post: 1597482, member: 29751"]Doug, consistency (reproducibility) is only one piece of the equation. Accuracy is the other. Being consistent isn't enough, if you are consistently below the true value (i.e., inaccurate). Consistency doesn't imply correctness...it merely means that you are able to repeatedly grade a coin the same. Just as easily you could be consistently wrong -- consistently low, or consistently high. And, even though you say it's an excuse, I will use it anyway -- to assess accuracy implies that there is a known <b><u><i>single</i></u></b> true gold standard of a coin's grade. Unfortunately, there is NOT a gold standard in coin grading because of subjectivity and personal opinions. You can argue until you are blue in the face that you still "ascribe" to the "good 'ole days of pure coin grading" before the market-grading TPGs, but your standard is just as arbitrary as the ones used by TPGs.</p><p><br /></p><p>PS -- I think it's easy to be consistent when your breadth of grades seems to consist of either AU58 or MS63 for stellar coins.
