<p>[QUOTE=&quot;Jaelus, post: 3652132, member: 46237&quot;]Ok so we have a sample size of 60, a mean of 64.5, and a standard deviation of 1.68. This means that the actual grade is between 64.1 and 64.9 with a confidence of 95%, between 63.9 and 65.1 with a confidence of 99%, and between 63.8 and 65.2 with a confidence of 99.99%.</p><p><br /></p><p><b><i>A 66 or higher isn&#039;t even on the table, statistically speaking.</i></b></p><p><b><i><br /></i></b></p><p>Of course, it is possible that there is just something about the coin that isn&#039;t conveyed with these high resolution photographs, but it seems more likely that it&#039;s simply overgraded.[/QUOTE]</p><p><br /></p>
