<p>[QUOTE=&quot;sgtbigred, post: 1743378, member: 27173&quot;]Warning for all &quot;coin doctors&quot;</p><p>Well it looks like the age old practice of doctoring coins will soon be much harder to accomplish. Especially for the older and rare coins that are often &quot;doctored&quot; to sell at a higher value.</p><p>Through modern technology a new process being introduced by PCGS for their &quot;Secure Plus&quot; grading will soon be in affect. This process uses dispersive X-ray spectrometry (EDX), Fournier Transform Infra-Red Spectral analysis (FT-IR), Raman Spectroscopy and other analytical techniques. In laymen terminology, it is similar to scanning with an electron microscope</p><p>　</p><p>To boil it down into a nutshell, it means it will now be harder for coin doctors to use various materials to conceal problems with a coin or alter its surface to improve its appearance in an attempt to artificially increase the coin&#039;s value.</p><p>Coin doctors have been know to use metals to enhance the head on a Standing Liberty quarter and even go as far as creating &quot;full bands&quot; on Dimes. Some of the items used are potassium, solder, indium and even Clorox<font face="Arial">®</font> .</p><p>Perhaps this new process even though an added cost, it will be well worth it especially if one wants to purchase a 1930 Standing Liberty with the designation of &quot;full head&quot;. You will know your coin has not been doctored and as another bonus, the current PCGS price guide for this coin already slabbed in MS-69 is $1,450 while one graded utilizing the Secure Plus system is valued at $2,000.</p><p>In the long run, a &quot;sniffed out&quot; coin is definitely a plus for any collector.[/QUOTE]</p><p><br /></p>
