<p>[QUOTE=&quot;ValpoBeginner, post: 2733235, member: 77066&quot;]ok i give up trying to convince you guys, instead I&#039;ve decided to end this.&nbsp; I&#039;ve read and studied too many books and articles to agree with you.&nbsp; But I do believe it is a matter of perspective.&nbsp; To me a tarnished coin is ugly because it&#039;s lost its lustre and eye appeal. A toned coin can be beautiful and quite a bit of eye appeal. (A big factor in grading) </p><p><br /></p><p>Let me&nbsp; explain.... </p><p><br /></p><p>But here&#039;s the real science.&nbsp; A chemical liquid or gas reacts with silver to forms a new compound and causes the layers to form.... the more silver molecules that have undergone this reaction the and the deeper the color we perceive. You see, the silver coming from the coin, and the reactant combine&nbsp; (most of the time silver sulfide) and if left unchecked becomes an ugly tarnish (too many layers). This is the point where the silver lustre of the coin corrodes and becomes a new compound, silver sufide or, take your pick of other silver molecules,&nbsp; and in fact turns into a new surface that the mint didn&#039;t intend. </p><p><br /></p><p>&nbsp; Toning does take away a few molecules of silver and chemically change some silver atoms into molecules of silver compounds but not enough to take away the lustre beneath the surface. </p><p><br /></p><p>So, since my profession is to help parties resolve disputes...ADR</p><p><br /></p><p>Let&#039;s just agree to disagree.&nbsp; A win win for both camps residing on both sides of the issue. You believe in a literal translation of &quot;tarnish&quot; in that a chemical process takes place from the beginning of Discoloration. </p><p><br /></p><p>&nbsp;And I think that tarnish, is a severe condition which begins at the point where it takes away MS status because it converts the surface metal into a new compound. </p><p><br /></p><p>So its just a matter of perspective on the </p><p>(-beginning-) of the process of when a coin begins to tarnish.&nbsp; That is all there is to say on this issue. </p><p><br /></p><p>&nbsp;My name on here may be ValpoBeginner, but I&#039;ve had quite a bit of life experience.[/QUOTE]</p><p><br /></p>
