<p>[QUOTE=&quot;desertgem, post: 1643683, member: 15199&quot;]If the main factor was the volume, he might be correct, but the main factor is the weight , or the specific gravity if one is concerned with the metallic content. The weight of the Morgan&nbsp; was set by law at 26.73 grams +/- 0.097 grams&nbsp; ~ so the $ could weigh as little as 26.663 grams&nbsp; to as much as 26.827 grams. With the mechanical actions to produce the planchet and the collar to limit diameter in striking/reeding, the height would probably be the larger variable as the dies might be set at a slightly differing height for each set of dies. The diameter was set at 38.5 mm, but no tolerance is given by the mint. If specific gravity is done by comparing the weight in air with weight while submerged in the required water, one could verify if the metal was approximately 90% silver. By using such mathematical determination of a dimension, one must determine if such are repeated with no variance. I don&#039;t know how the calculus professor would assign tolerances for the measurement as the mint assigned them for the content ( weight and silver/copper percentages and set the diameter at 38.5 mm. But good mind problem.</p><p style="text-align: left"><span style="color: #000000"><br /></span></p> <p style="text-align: left"><span style="color: #000000"><br /></span></p><p>[/QUOTE]</p><p><br /></p>
