<p>[QUOTE=&quot;ksparrow, post: 646616, member: 7638&quot;]Sometimes you can infer, or be certain, that a coin has been cleaned from photos, but many times you cannot. The only way to tell for certain is to look at the coin in a dim room, with a low power glass and a point source light (LED or halogen) while moving the light or the coin around, tilting and rotating it. Cleaning will be seen as long, wispy parallel lines that sweep across both the fields AND the devices, not as the random, short, scattered hairlines from circulation. Sometimes, cleaning was done on a specific area- usually in the field-- and will appear as a dense cluster of fine lines. If the coin has retoned over the marks- as appears to be the case with the coin in the o.p.-- the signs of cleaning can be nearly invisible at arm&#039;s length. IMO, the PCGS &#039;genuine&#039; service is a valuable one. You simply CANNOT be certain from photos that a coin has NOT been cleaned. For instance: </p><p><br /></p><p><img src="http://i162.photobucket.com/albums/t277/cks2007/quarters/quarter1806rev.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="http://i162.photobucket.com/albums/t277/cks2007/quarters/quarter1806obv.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>This coin has numerous fine hairlines under the toning.</p><p><br /></p><p><img src="http://i162.photobucket.com/albums/t277/cks2007/Seated%20Dollars/SeatedDollar1872obv.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>Using the technique mentioned earlier, fine wispy hairlines can be seen sweeping diagonally across the entire obverse, indicating a cleaning, but they are not visible in the photo.[/QUOTE]</p><p><br /></p>
