<p>[QUOTE=&quot;desertgem, post: 1254535, member: 15199&quot;]Since the only difference is mainly intent, which we can&#039;t know, it is not a reasonable question. This is not one of the &quot;Dummies guides to toning&quot; experiments which most can detect. So if it is really album toned over many years, or album toned over 1 week ( with help), or toned in a few hrs&nbsp; by gaseous perfusion by an expert, can not be readily decided. So MA is the only&nbsp; designation I would give it. My opinion is that chemistry of toning is just chemistry. Careful application can produce the same effects as nature. Most of the old sayings about how to tell, were based on liquid applied chemicals, and are not applicable if the chemicals are applied in a gas. If I needed and wanted the coin, I would buy it. If it wasn&#039;t in a good TPG slab, I wouldn&#039;t.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
