<p>[QUOTE=&quot;lkeigwin, post: 1598148, member: 30400&quot;]A forum member asked me to do a little test with MS70 and copper. So I did.</p><p><br /></p><p>I chose four coins. A full red, a RB with common toning, another RB with dark tone, and a full BN. Each coin was swabbed with MS70, and then the solution was removed after a several seconds, using a Qtip. All coins were rinsed in water and air dried before reimaging. Before and after results follow. The image colors are correct.</p><p><br /></p><p><br /></p><p>The 1920 had the common look of a RB Lincoln with a mix of toned brown and original mint red. It had a very noticeable change with striking beet red, purple and blue.</p><p><br /></p><p><br /></p><p>The RD 1940-D lost its pumpkin orange color. In hand it looks pretty much like an ordinary red cent, though with a loupe and in these images you can see pale blue spots.</p><p><br /></p><p><br /></p><p>I didn&#039;t take a hard look at the darkly toned 1930 before I chose it. After seeing the results I believe the toning it had was organic and probably would have dipped off in acetone. I used several swabs to clean it up. Not sure there&#039;s much to conclude about this one.</p><p><br /></p><p><br /></p><p>After applying MS70 to the brown 1952 it appeared to have much more blue than the images suggest, but a subtle, powdery blue, not electric like the 1920. I propped it on a paper clip to get a little angle and shot two more pix. Didn&#039;t make a big difference.</p><p><br /></p><p><br /></p><p>A fun morning experiment. Maybe I&#039;ll do something similar with acetone, eZest, Blue Ribbon, CoinCare and Verdigone.</p><p><br /></p><p><br /></p><p>Just my two cents...well, four.</p><p>Lance.</p><p><br /></p><p><br /></p><p><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08507_zps6d389c07.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08508_zps09b3c48a.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08509_zps6605b5f0.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08510_zps5dc1ae75.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08511_zpsa2f5d663.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08512_zpsde9f90e1.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08517_zps1972f0fc.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08518_zps9e88c3f1.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08513_zpsf8872eca.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08514_zps143e585d.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08519_zps5cbe4fdf.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08520_zps5f9ca0f6.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08515_zpsde43359a.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08516_zps38a08930.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08523_zpscfb8b253.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08524_zps9ba5ab46.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08525_zps004b0a23.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /><img src="http://i244.photobucket.com/albums/gg37/lkeigwin/dumb%20stuff/DSC08526_zps3e3e350d.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /> [/quote][/QUOTE]</p><p><br /></p>
