<p>[QUOTE=&quot;GDJMSP, post: 4590445, member: 112&quot;]Goldfinger I don&#039;t know how you use the word &quot;weight&quot; in this context, but if the index is weighted that means that 1 particular item counts more, or less, than another particular item. But that is not the case PCGS 3000 Index - not in any way.</p><p><br /></p><p>The movement of the index is tracked based on the value of the whole - that&#039;s all it is. A simple way of explaining it is that you take 3000 coins in given grades, and you put them all into 1 basket. The value of each individual coin added together determines the value of the basket. And it is that total amount that moves up and or down over time - and that&#039;s what&#039;s tracked - 1 single dollar figure.</p><p><br /></p><p>This is why I say there is no weight. No individual item counts any more or any less than any other item. It&#039;s not a &quot;price weighted&quot; index, it&#039;s a &quot;price based&quot; index. And they do not mean the same thing.[/QUOTE]</p><p><br /></p>
