<p>[QUOTE=&quot;900fine, post: 477981, member: 6036&quot;]Well, on another thread, borgovan shared a beautiful toned Buffalo 5c he scored. So, that got me thinking (and you know how dangerous <i>that</i> can be...)</p><p>&nbsp;</p><p>For some reason, certain coin types are more &quot;prone to tone&quot; than others. For instance, there are some great Buffalo 5c toners out there, but fewer Shield and V 5c.</p><p>&nbsp;</p><p>Lots of toned Morgans, but almost no Peace.</p><p>&nbsp;</p><p>Which coin types are most likely to be found with great NT ?</p><p>&nbsp;</p><p>Why are they more prone to tone ?</p><p>&nbsp;</p><p>One expects different toning from different alloys... but even <b>different types of the same composition exhibit different toning propensity.</b> For instance, both Morgan and Peace are 900 fine silver, the rest copper. But Peace rarely NT, but many Morgans do.</p><p>&nbsp;</p><p>My guess - it is mostly related to the differences in the nature of minting or the design.</p><p>&nbsp;</p><p>It seems to me that once a coin has lost it&#039;s original surfaces due to cleaning or other abuse it has less chance at rainbow NT. It may re-tone, but not rainbow. Is that true ? If so, why ? </p><p>&nbsp;</p><p>What&#039;s happening on the surface skin / texture that prevents NT on cleaned coins ?[/QUOTE]</p><p><br /></p>
