I can learn from you so I don&#039;t get a &quot;time out&quot; again.&nbsp; Further more, I don&#039;t wish to write about another different coin right now.&nbsp; </p><p><br /></p><p><br /></p><p><br /></p><p><br /></p><p>I wish you would allow me to insert my comments in color into your quote as it saves me time.&nbsp; Nevertheless:</p><p><br /></p><p>Corrosion starts as a chemical reaction on a surface.&nbsp; Much of the time, the byproduct (think of rust) builds up in layers ABOVE the original surface (as on your coin) as the reaction continues.&nbsp; Additionally, the original surface at the point of the corrosion is etched away.&nbsp; In many cases, when corrosion is removed from the surface, only the pitting remains.&nbsp; Think of a &quot;porous&quot; Large cent.</p><p><br /></p><p>Your OP coin is FULLY STRUCK with no weakness.&nbsp; A black color on most coins is a POISON and usually indicates oxidation that has gone so far as to be unattractive and damaging to its surface.&nbsp; IMO, that is the obvious case with your Large cent.</p><p>My mind is still slightly open - the thickness of a hair. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" />&nbsp;&nbsp; Hope you can take a sharp image.&nbsp; BUT if you&#039;ll agree the black area is raised, I see no way to change my opinion.</p><p><br /></p><p>I&#039;m going to look around here for some corroded copper to photograph but at the moment our safes are closed. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie15" alt=":arghh:" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
