<p>[QUOTE=&quot;desertgem, post: 515284, member: 15199&quot;]Doug, I have never personally used Biox, and I can&#039;t find any physical or chemical properties on the net that might give an idea as to it&#039;s makeup. The photos that I have seen of Biox treated coins, almost all ancients I must admit , really ended up with a very definite &quot;pinkish &quot; tone, I usually associate with an acid or a chemical that readily reacts with Cupric oxide. Maybe someone would want to do an experiment on different dilutions of Biox and see if they can find a range that would remove the verdigris and not turn the copper pink. </p><p><br /></p><p>&nbsp;&nbsp;&nbsp; I do agree with you on the &#039;08s.&nbsp; But I am surprised that I have had a few attractive offers on it ( even with known history).</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
