<p>[QUOTE=&quot;TypeCoin971793, post: 3067915, member: 78244&quot;]I think this would be an interesting discussion. What are your definitions for a “cleaned” coin? Are there different levels of a “cleaning?” Should other terms be&nbsp; used? What makes a coin “cleaned?” At what point does the coin become damaged? Etc.</p><p><br /></p><p>Several of us have different definitions. I know that several of us have differing opinions,&nbsp; so I look forward to the debate.</p><p><br /></p><p><br /></p><p>My definitions:</p><p><br /></p><p>A coin has been “cleaned” when any material has been intentionally removed from the coin. Thhis includes both a harmless acetone dip and vigoroous scrubbing with steel wool.</p><p><br /></p><p>A coin has been “dipped” when a coin was immersed into a chemical agent to remove material from the surface.</p><p><br /></p><p>A coin has been “overdipped” when the chemical agent has removed enough of the metal on the surface to give the coin an annatural appearance. Usually, the mint luster has been chemically stripped, giving the coin a dull, lifeless appearance. Any coin below AU-55 that has been dipped is automatically included in this category.</p><p><br /></p><p>A coin has been “abrasively cleaned” when an abrasive has been used to srape away some contaminants or the top layer of metal. An abrasive can be anything from your finger to sandpaper. Hairlines will be left from the process.</p><p><br /></p><p>A “harshly-cleaned” coin is a subcategory of “abrasively cleaned” where the abrasive used or the scrubbing done has left severe hairlining.</p><p><br /></p><p>A coin is “polished” when a chemical agent or cleaning tool is used to make the coin&nbsp; uniformly shiny.</p><p><br /></p><p>A coin is “whizzed” when a tool (usually a high-RMP rotational tool like a Dremel) is used to alter the surface to give a coin a fully-lustrous appearance.[/QUOTE]</p><p><br /></p>
