<p>[QUOTE=&quot;GDJMSP, post: 845155, member: 112&quot;]If you mean harsh cleaning - it would definitely change it. If you mean proper cleaning - I doubt it would change anything in regards to the fingerprint.</p><p><br /></p><p>As for toning - that would depend on the toning and the coin. Some toning is heavy/thick enough to cover up some things on coins. So I would have to believe that if a heavily toned coin were scanned/fingerprinted -then dipped - it would be possible that the software would see it as a different coin. </p><p><br /></p><p>But it would also depend on if there was anything being coverd up by the toning. If there wasn&#039;t - then it would, or rather should, see it as the same coin.</p><p><br /></p><p>However - proper cleaning and/or the removal of toning can and often does change the grade of a coin. The change can be to the upside or the downside. So theoretically even though a coin could have the same fingerprint - it could have two different grades - and legitimate grades in both cases.[/QUOTE]</p><p><br /></p>
