<p>[QUOTE=&quot;Marine1, post: 2497152, member: 80257&quot;]Sir,</p><p>You are true believer and absolutely correct about the breed apart and ALL of the TPG,ers, I love Roses and toned or rusted coins depending on ones viewpoint.</p><p>A small factoid about rusty Morgans, not one in a million is the same or even close and also varies from batch run to batch run, for at least 4 reasons that I can think of. Only one gas at .02ppm to 1 ppm can tone a pre 1899 cc, s or ?? Morgan and that is H2S as Au/90% +7 to 8% Cu does not react with any other gas at least not au natural. after 1899 all the Au/Cu mixes for coins were more tightly controlled and all of the coins were minted from that mix.</p><p>All that to say that 90% Au coins after and up to today have a definite pattern of toning givin the same amount of time, temperature and storage method for&nbsp; approx 15 yrs.</p><p>One last note before beauty sleep I &quot;just to prove a point &quot; have invested in photo spectroscopy and IP spec equipment to see if the PCGS &quot;sniffer&quot; works and have proven at least to myself they have too many false positives or red dots as they call them and the only way they can accurately determine the chemistry of coins is a 300-400K Gas Chromatograph which would raise the price to 250.00 minimum per coin , more later on this note if anybody has any interest.</p><p>M1[/QUOTE]</p><p><br /></p>
