<p>[QUOTE=&quot;-jeffB, post: 24595980, member: 27832&quot;]The people who&#039;ve actually been trained on the ray-gun would know better than I do, but I&#039;m pretty sure that a plated layer of a higher-atomic-weight and denser metal like silver would partially <i>shield</i> the underlying base metal, especially if the the plating is fairly thick. So if you&#039;ve got a layer of 100% silver over a copper core, it might well read as some intermediate percentage of silver. Did they say what the other 23% read as?[/QUOTE]</p><p><br /></p>
