<p>[QUOTE=&quot;LostDutchman, post: 996112, member: 16994&quot;]From time to time we at the shop run across coins that are really nice but because of improper storage have issues. I have to preface this post by saying that if you don&#039;t know what you are doing then you should NEVER EVER attempt to clean or conserve a coin. This is a nice frosty cameo 1956 half dollar. This coin sat until this afternoon in an OLD ANACS holder. It had developed haze and PVC contamination over the years. The PVC had also caused the coin to tone unattractively in the holder. The coin was first soaked in acetone to remove the PVC and haze and then dipped to remove dark toning left by the PVC exposure. These pictures were taken with the same lighting and settings on the camera. The blue look on the before picture is the haze. </p><p><br /></p><p>Dipped? </p><p><br /></p><p>Yes I have dipped this coin... There are VERY few circumstances where I dip coins... a coin has to be really nice with unattractive toning to even be considered for a dip... and then it is VERY fast and neutralized quickly. </p><p><br /></p><p>I think this posting is going to spark some good discussion. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" /> </p><p>[ATTACH]96109.vB[/ATTACH]</p><p>[ATTACH]96108.vB[/ATTACH][/QUOTE]</p><p><br /></p>
