<p>[QUOTE=&quot;SuperDave, post: 2234317, member: 1892&quot;]Whizzing is a harsh mechanical polishing process which involves the use of a power tool to alter the surface of a coin. Its&#039; goal is not about cleaning; it&#039;s about &quot;improving&quot; the overall look of the coin. I consider it an extreme form of polishing, not cleaning.</p><p><br /></p><p>The coin here has had an unfortunate and accidental encounter with a brush or similar. There is no evidence in any of these images of a condition requiring cleaning, no hairlines except in the affected area. Chances are it was one swipe of whatever did it.[/QUOTE]</p><p><br /></p>
