<p>[QUOTE=&quot;GDJMSP, post: 1981123, member: 112&quot;]There was a study done at a university some years ago, the conclusion was that the numbers (pop numbers) were probably off by 20% or so.</p><p><br /></p><p><br /></p><p><br /></p><p>Yes.</p><p><br /></p><p><br /></p><p><br /></p><p>Depends. With grades anywhere say up to 66 - it has little effect at all. It also depends on the coin in question to a degree. But there was a case where increasing pops had a huge effect on values, only it wasn&#039;t due to resubmissions, it was due to a change in grading standards. When the TPGs changed their grading standards and the pop numbers of 70 graded coins started climbing, increasing by as much 400-700% in a single year - the value of those 70 graded coins fell off a cliff !</p><p><br /></p><p><br /></p><p><br /></p><p>They will correct them if old slab labels are sent in, other wise no they do not.</p><p><br /></p><p><br /></p><p><br /></p><p>Yes.</p><p><br /></p><p><br /></p><p><br /></p><p>Total number of graded coins are provided in the pop reports, but that is only part of the entire census for any given coin. Like Tom said, the entire census for some coins is estimated by specialists.</p><p><br /></p><p>But let&#039;s gets down to brass tacks, what exactly is it that you are trying to figure out ? It&#039;s probably easier to answer to real question directly than going the roundabout way to get there.[/QUOTE]</p><p><br /></p>
