<p>[QUOTE=&quot;Oldhoopster, post: 8638047, member: 84179&quot;]I&#039;ve seen then slabbed as well. It may be ANACS, but I&#039;m not certain.&nbsp; But how did they determine it was brass?&nbsp; Do they have someone with calibrated eyeballs?&nbsp; Do they have CIELAB color maps correlated to brass plating on cents?&nbsp; Or are they just making a BEST GUESS?&nbsp; Its a guess.&nbsp; </p><p><br /></p><p>I&#039;ll swear up and down that I have a couple brass plated cents, but I have NO PROOF.&nbsp;&nbsp; I worked for a fortune 500 company that had over 1000 people working at their R&amp;D campus. They had every type of analytical equipment you could imagine.&nbsp; But I couldn&#039;t get surface compositions unless we cut up the sample.&nbsp; It&#039;s easy if you cut up the sample, but doing non destructive testing?&nbsp; Not something I know of and my guess is ANACS doesn&#039;t know either.[/QUOTE]</p><p><br /></p>
