<p>[QUOTE=&quot;GDJMSP, post: 3578010, member: 112&quot;]Yes Michael, I am very well aware of that technicality. But the plasticizer you&#039;re talking about, in discussions and ordinary conversation it&#039;s pretty much always simply referred to as PVC, and or PVC residue so as to avoid confusion.</p><p><br /></p><p>edit - I should have added that is good to add the info you did for those who were not aware of it.</p><p><br /></p><p><br /></p><p><br /></p><p>Afraid I disagree with ya on this point. It does not leach out as a liquid but as a gas. Then the gas condenses on the coin and turns into a viscous liquid as greater and greater amounts of it accumulate.</p><p><br /></p><p>In the beginning that liquid is crystal clear, almost invisible to the naked eye. It is only after it has been there a while that it takes on its greenish shade of color. And over time the greed shade fades, the substance dries out and can even become flaky in nature, and it often becomes a tan color, then brown, and in some cases it can even become quite dark, almost black.</p><p><br /></p><p>The point here is that PVC residue is not static in color nor form, it is ever changing in color and form as the chemical reactions occur over time. The reason it is important that folks know this is so it can be more readily recognized in any and all of its forms and colors - all of which are harmful to the coins.[/QUOTE]</p><p><br /></p>
