I don&#039;t see as well as I used to and I use an illuminated loupe 20x to help me see better details. From my understanding the tpg&#039;s use 10x or possibly higher.&quot;</p><p><br /></p><p>AFAIK, Most TPGS graders don&#039;t use a hand lens for many coins.&nbsp; Especially those grading the larger coins and &quot;moderns.&quot;&nbsp; The ANA recommends 5X.&nbsp; With 20X you only see tiny parts of a coin all at once and it limits the amount of light on the coin.&nbsp; THE ONLY use of a 20X glass - lighted or not - is for micro varieties and authentication. You cannot properly grade a coin with one.&nbsp; I use BOTH a 7X hand lens with incandescent light and a stereo microscope set at 7X with florescent light to examine virtually every coin we get.&nbsp; </p><p><br /></p><p>Btw, if you cannot see the characteristics of a coin&#039;s surface with 5X or 10X max, you may have a serious eye problem.[/QUOTE]</p><p><br /></p>
