<p>[QUOTE=&quot;desertgem, post: 1504890, member: 15199&quot;]Welcome to the forum!.&nbsp; Mold shouldn&#039;t be growing on the coin. If it is, it is far too wet. Dirt can affect the preceived value as buyers will suspect it of hiding damage and being a result of poor care. there are safe ways to alleviate these problems. Physical damage such as scratches, dings, grafitti ( visible scratched letter or words ) chemical acitivity such as acids or other chemicals , and many other things can decrease the value of the coin.</p><p><br /></p><p>Now the harder question. Patina/Tarnish/toning/corrosion are all the same basic chemical processes whether natural such as in a paper envelope for 40 years or exposed to the same chemicals for a few minutes, the processes are the same. If it is the &quot;tarnish/toning&quot; aspect, very little of the coin metal surface is affected, and may raise the value of the base coin depending on its attractiveness to the buyer. However, if it extends too long and damages the surface of the coin, it is forever damaged, and the value decreases. The use of silver dips such as acids or cyanide solutions has a long history and are considered acceptable by most as long as it isn&#039;t too extensive to alter the surface and affect the luster of the silver coin. Too much and a reduced luster will affect the value negatively. </p><p><br /></p><p>Just a synopsis to help answer some of your questions. </p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
