(The original surface could be grime from circulation or toning.) </span></font></font></span></p><p><span style="color: #000000"><font face="Arial"><font face="Tahoma"><span style="color: #000000"><br /></span></font></font></span></p><p><span style="color: #000000"><font face="Arial"><font face="Tahoma"><span style="color: #000000"><br /></span></font></font></span></p><p><span style="color: #000000"><font face="Arial"><font face="Tahoma"><span style="color: #000000">Many substances are used to &quot;dip&quot; coins, jewelry cleaner, bleach, Brasso, etc, and each give the coin a distinct appearance. With a little experience and a lot of caution, a buyer can learn to distinguish the differences between a &quot;natural&quot; coin or one that has been tampered with.</span></font></font></span></p><p><span style="color: #000000"><font face="Arial"><font face="Tahoma"><span style="color: #000000"><br /></span></font></font></span></p><p><span style="color: #000000"><font face="Arial"><font face="Tahoma"><span style="color: #000000"><br /></span></font></font></span></p><p><span style="color: #000000"><font face="Arial"><font face="Tahoma"><span style="color: #000000">If a coin has a lot of wear and looks white, or the surface is too shiny or clean, then it may have been dipped or chemically altered. Most coins, altered in this method, will have a distinct &quot;flat&quot; luster due to the chemical causing microscopic etchings in the metal surface. Most normal coins will have a glossy or smooth or frosty-lustrous appearance to their surfaces. It takes a little experience to differentiate between dipped and normal coins.</span></font></font></span></p><p><span style="color: #000000"><font face="Arial"><font face="Tahoma"><span style="color: #000000"><br /></span></font></font></span></p><p><span style="color: #000000"><font face="Arial"><font face="Tahoma"><span style="color: #000000"><br /></span></font></font></span></p><p><span style="color: #000000"><font face="Arial"><font face="Tahoma"><span style="color: #000000">Ebay poses some difficulties in identifying dipped coins, because identifying the true condition of a coin is almost impossible via pictures. Couple that with the poor photographs found on ebay, presents a challenge for any coin collector. It&#039;s recommended that beginning buyers purchase graded and authenticated coins online first, before venturing into the realm of raw coins.</span></font></font></span></p><p><font face="Tahoma"><span style="color: #000000"><br /></span></font></p><p><font face="Tahoma"><span style="color: #000000"></span></font>[/QUOTE]</p><p><br /></p>
