<p>[QUOTE=&quot;desertgem, post: 912159, member: 15199&quot;]If they are above beginner Doctors level in skill and technique, using the correct chemicals, the AT will look the same as a NT of similar toning stage in that time. The difference will be the environment and storage, not how the initial toning was produced. It can be the very same chemical reaction.</p><p><br /></p><p>The PCGS has publicly disclosed that very sophisticated means, beyond the average collector usage&nbsp; ( I have lasers, etc., but I don&#039;t have the alignment and precision controllers needed to alter the surface of a coin). Likewise I am sure if we could be the fly on the wall of a high class AT operation, we would see methods and devices far more sophisticated than most could imagine. It is not just a few people sitting around, dunking coins in sulfides. Eventually the large percentage of collectors that say they can tell AT from NT will realize that almost none can. Yes, this will affect the toned coin market, just as this PCGS action will affect the high end market. I think Toning will eventually have to be either &quot;Market acceptable&quot; or &quot;Market unacceptable&quot; to be realistic.</p><p><br /></p><p>Maybe if PCGS didn&#039;t have to pay out the millions to repurchase the altered coins, it would still be a &quot;trade secret&quot;.
