<p>[QUOTE=&quot;physics-fan3.14, post: 3185212, member: 19165&quot;]I use the term &quot;harshly cleaned&quot; whenever the surfaces have been seriously disturbed by the cleaning. That could be hairlines from steel wool, fine hairlines from a jeweler&#039;s cloth, or some other method that&#039;s stronger than a dip. A dipped coin would just be &quot;cleaned.&quot; </p><p><br /></p><p>In this case, it appears that some sort of method was used on the top half of the reverse that left the surfaces rough. This could be some sort of brush, but I don&#039;t see hairlines. I&#039;m guessing it was some sort of baking soda or chemical concoction to remove environmental damage - but it left the surfaces devoid of luster. Thus, I call it harshly cleaned.[/QUOTE]</p><p><br /></p>
