<p>[QUOTE=&quot;900fine, post: 504189, member: 6036&quot;]Do you adjust for varieties ?</p><p>&nbsp;</p><p>For instance: in Heritage price histories, sometimes they seperate a given issue into various specialized die varities, sometimes they don&#039;t. In cases where they don&#039;t, a stack of sales data will mix coins of differing rarity. One can have an r.1 in with an r.2 or r.3, which is not always obvious. Clearly, this throws off the numbers.[/QUOTE]</p><p><br /></p>
