<p>[QUOTE=&quot;mrbrklyn, post: 448190, member: 4381&quot;]I don&#039;t think either of these models are likely realistic.&nbsp; One thing that is almost surely a result of the minting process which involves several tons of prssure, if I understnad correctly what the mint does, is that the molecules on the surface with align as they do when metal is molten.&nbsp; Once aligned, they are in a highly ordered state.&nbsp; there is a lot more chemical potential in a system in an ordered state than one which is not.&nbsp; That fact alone would make dipped coins more resistant to toning.[/QUOTE]</p><p><br /></p>
