<p>[QUOTE=&quot;Collector1966, post: 1191064, member: 17919&quot;]There are various types of toning. In general, it is divided into &quot;natural toning&quot; (NT), and &quot;artificial toning&quot; (AT). Artificial toning, which is done with chemicals in an accelerated process, generally decreases the value of a coin if it is recognized as artificial toning, especially if it is used to hide defects, wear, etc.</p><p><br /></p><p>Natural toning may or may not enhance the value of a coin. When I was starting to collect coins, the unsightly brown/black streaks and spots on coins were called &quot;tarnish&quot; and tarnish was considered to reduce the value of the coin. On the other hand, sometimes the natural process of toning creates vivid colors, even a rainbow effect, and this can enhance the value of a coin.[/QUOTE]</p><p><br /></p>
