<p>[QUOTE=&quot;Oldhoopster, post: 2651285, member: 84179&quot;]It&#039;s hard to tell from pictures, but dull surfaces can be a sign of heavy dipping.&nbsp; Luster is due to microscopic lines caused be the metal flowing from the center towards he rim during striking.&nbsp; Tarnish is usually some sort of silver sulphide (Ag2S).&nbsp; The sulfur reacts with the silver atoms on the surface of the coin forming toning.&nbsp; The thicker the Ag2S, the darker the toning.&nbsp; Dipping a coin removes the Ag2S.&nbsp; This actually removes some of the silver from the surface because it reacted to form the toning.&nbsp; Remove enough of the silver that causes the luster and you get a dull coin.</p><p><br /></p><p>I think it&#039;s been dipped and will come back as cleaned, but can&#039;t say for certain.[/QUOTE]</p><p><br /></p>
