<p>[QUOTE=&quot;GDJMSP, post: 2116655, member: 112&quot;]Carbon spot - that&#039;s another one of those terms that has come to be used to describe many different things caused by many other different things. </p><p><br /></p><p>Originally a carbon spot was just that, a tiny speck of carbon. It came to be as a result of a tiny speck of impurity in the metal of the planchet that corroded over time and became carbon after the coin was struck. They did not grow, they could not be removed, and there was nothing that could be done about them.</p><p><br /></p><p>But as often happens, over the course of time any small dark spot on a coin came to be called a carbon spot because people had heard or read the term before, saw a dark spot on a coin and not knowing what it really was, said - oh, that&#039;s a carbon spot - when it wasn&#039;t a carbon spot at all.</p><p><br /></p><p>In today&#039;s world it&#039;s become a catch-all term and is used to describe all kinds of things. Such as: saliva droplets, small specks of any organic material, actual carbon spots, remnant specks of dark toning mostly removed by dipping, the list goes on. </p><p><br /></p><p>And yes, spots caused by some of these things can be removed, others cannot. And in some cases even after they are removed a corresponding light spot where the dark spot used to be will be left on the coin. So there is not always a benefit in trying to remove them, and in some cases it may even turn out worse. Most of this can be determined beforehand if you know what you are looking at when you see it. If you don&#039;t, then you should leave it for others to decide.[/QUOTE]</p><p><br /></p>
