<p>[QUOTE=&quot;fretboard, post: 4601582, member: 19765&quot;]Those guns are super effective at reading the amount of all the metals in that gold coin.&nbsp; Personally, I don&#039;t think there&#039;s anything at all wrong with that gold coin, but just to be safe, if it was mine, I would have it scanned.&nbsp; They couldn&#039;t keep selling XRF spectrometers for thousands of dollars if they didn&#039;t work.&nbsp; Years ago, if you mentioned an XRF spectrometer on this forum you rec&#039;d all kinds of flak.&nbsp; Not so much anymore because people are finding out that it&#039;s a very effective tool![/QUOTE]</p><p><br /></p>
