<p>[QUOTE=&quot;desertgem, post: 640775, member: 15199&quot;]Please know that I am not opposed to your idealism in this matter. I certainly do not condone misleading anyone into a purchase, but as many others have noted ( including myself) in other threads, there is no currently available means of determining how much time&nbsp; or chemical reaction has been involved in any toned coin, so there is no scientific way of determining very good AT from NT. V/V, there is no way of determining NT from AT scientifically, it is all subjective decisions rather than objective.</p><p><br /></p><p>Tone doctors are like a baseball pitcher going against the Yankees ( PCGS,NCG). If they are little league, they will be &quot;No Graded&quot;, same for HS level. At the college level, maybe some hit, some strikeout, but a major league pro can do very well against them. Many know as much about chemistry as a chem professor, or they may be one. </p><p><br /></p><p>They will check the coin if slabbed to see if photos are on the net or at the services and won&#039;t use one that was recently graded. Check if raw coins have been on ebay, etc. Prepare the coins ( not explained as not necessary for argument)</p><p>Set up a vacuum chamber to remove the air slowly from slabs, and then release &quot;toning chemicals&quot; as a gas into the chamber. Toning can be done in minutes or more slowly over days or weeks ( How is this different from putting into an old album or setting on a windowsill, or oak plank). Prepare coin for sale ( again not necessary for argument).&nbsp; The only difference is really intention and time, factors impossible to discern...except for the time factor if you can find the coin was photographed white a couple of months ago and photos are available.</p><p><br /></p><p>My apology to those who feel they can tell the difference by looking, as my feeling is that you are looking at minor league doctor&#039;s work. Either enjoy or hate them for their appearance.</p><p><br /></p><p>If someone sells a coin that is suspected of being AT, and does not claim it is NT, do they have a responsibility to the buyer?</p><p><br /></p><p>If you said yes, does not the same logic apply to a person who has a suspected dipped coin that is bright white? Why is dipping different than toning? </p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
