<p>[QUOTE=&quot;NPCoin, post: 4585427, member: 5629&quot;]Not only that, but the grading was admittedly liberal and arbitrary.&nbsp; It was a &quot;formulated&quot; form of grading.&nbsp; You can pick up a copy of the <i>N.C.I. Grading Guide</i> from 1986 and get all the details there.</p><p><br /></p><p>In a nutshell, the N.C.I. grading was based on four factors formulated with a weighing ratio of 2:1:1:1 with <b>surface preservation</b> receiving twice the weight in the formula as <b>strike</b>, <b>lustre</b>, and <b>eye-appeal</b>.&nbsp; Now, within each of these factors, there were five possible points that may be awarded.</p><p><br /></p><p>After determining the amount of points to award for each grading factor of the coin (each side graded separately), the points would be added up (with surface preservation receiving 2x the points).&nbsp; Grades from MS60-67 would then be assigned based on the total amount of points tallied for the obverse then reverse based on a skewed scale from 5 to 25.</p><p><br /></p><p>Read the book and it&#039;ll probably make even less sense to you!&nbsp; <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie26" alt=":bookworm:" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
