<p>[QUOTE=&quot;GDJMSP, post: 1756949, member: 112&quot;]</p><p>&nbsp;</p><p>I have been researching this topic all day. My coin has numismatic value and I want to preserve it correctly. Even if preserving it correctly means not doing a damn thing. But I am flabbergasted that I can&#039;t find anything online about how to preserve or clean a &quot;colorized&quot; silver coin.<font size="3"><font face="georgia"><span style="color: #333333">&nbsp; </span></font></font>[/quote]</p><p>&nbsp;</p><p>&nbsp;</p><p>Sorry, can&#039;t be done. Doing nothing is your only choice with that coin. </p><p>&nbsp;</p><p>You see, the body oil that causes fingerprints is acidic. And once the fingerprint has been on the coin for a while the acidic oils actually etch the print down into the metal itself, just as any acid would. And once that happens the only way to remove fingerprints from a coin is to remove the top layer of the metal itself thus taking the fingerprint with it. That&#039;s what using a commercial coin dip (acid) does, it strips away the top layer of metal. Which is why the process will remove toning.</p><p>&nbsp;</p><p>But you have a two pronged problem - a fingerprint and applied coloring. So there is no way to remove one without removing the other as well.</p><p>&nbsp;</p><p>But you still have a solution, which I mentioned earlier. Sell or trade the coin and get one you like.[/QUOTE]</p><p><br /></p>
