<p>[QUOTE=&quot;Coinchemistry 2012, post: 1980861, member: 28107&quot;]I said under normal numismatic storage conditions, meaning those used by serious numismatists.&nbsp; Under proper storage, NT can be virtually arrested and it will change very little even in several decades.&nbsp; I don&#039;t disagree that some AT can be stable, but much of it isn&#039;t.&nbsp; Either way, it directly challenges the poster I quoted who treats all AT alike and equates it with natural toning.&nbsp; His claim is specious at best.&nbsp; Chemically identical substances should act the same under the same reaction conditions.[/QUOTE]</p><p><br /></p>
