<p>[QUOTE=&quot;Vess1, post: 487474, member: 13650&quot;]Instead of going off track on another post, I decided to start the topic up again on artificial toning.&nbsp; I was reading an article online that I thought was interesting and I was wondering if anyone else has anything to add?&nbsp; Some pics showing some known AT&#039;d coins would be great as well.</p><p><br /></p><p><br /></p><p>&nbsp;&quot;Although the majority of toned silver dollars on the market&nbsp; &nbsp; have acquired their coloration over a long period of time, the beginning&nbsp; &nbsp; collector must beware of artificially toned coins.&nbsp; &nbsp; <p style="text-align: left"> The parameters which determine a coin to be artificially&nbsp; &nbsp; toned remain a topic of hot debate, but for the purpose of the present&nbsp; &nbsp; discussion, we shall define artificial toning as any rapid chemical,&nbsp; &nbsp; electrical or otherwise unorthodox process which produces or induces&nbsp; &nbsp; coloration on one or more surface of a coin.</p> <p style="text-align: left"><br /></p> <p style="text-align: left"><br /></p> <p style="text-align: left">&nbsp;Since storing silver dollars in a&nbsp; &nbsp; Mint bag, an original roll, a paper envelope or an album allows toning to form&nbsp; &nbsp; over a period of many years, such toning must be considered natural. </p><p>&nbsp;&nbsp; <p style="text-align: left"> Artificial toning frequently yields intensely fluorescent&nbsp; &nbsp; purple, blue or red toning. Furthermore, coins which have been literally&nbsp; &nbsp; &quot;baked&quot; display brown or deep gold coloration. </p><p>&nbsp;&nbsp; <p style="text-align: left"> Other artificially toned dollars show a hazy or smoky patina&nbsp; &nbsp; on the surface. Simply smelling your coin is an excellent way to detect&nbsp; &nbsp; spurious coloration, If your coin smells electrical, burned, or generally&nbsp; &nbsp; &quot;cooked&quot;, beware! If you have any questions concerning the veracity of a toned&nbsp; &nbsp; coin, consult your local professional numismatist. </p><p>&nbsp;&nbsp; <p style="text-align: left"> Certification of toned silver dollars a third-party grading&nbsp; &nbsp; service remains the best method of weeding out artificially toned coins. Since&nbsp; &nbsp; none of the major grading services will encapsulate specimens with even&nbsp; &nbsp; &quot;questionable&quot; toning, collecting only &quot;slabbed&quot; coins may be your best&nbsp; &nbsp; insurance policy.&quot;</p> <p style="text-align: left"><br /></p> <p style="text-align: left"><br /></p> <p style="text-align: left"><br /></p><p>&nbsp; I also read something about spotting being an indicator.&nbsp; Spotting is a screw up that has to be left or attempted to cover up, typically on higher dollar coins.&nbsp; Naturally toned coins should not exhibit any spotting.</p><p><br /></p><p>&nbsp;I will continue to add to this thread if I find anything interesting.[/QUOTE]</p><p><br /></p>
