<p>[QUOTE=&quot;cpm9ball, post: 1317848, member: 24633&quot;]The fine hairlines from whizzing don&#039;t necessarily have to be in a circular pattern. A fine brush or buffing (wheel) attachment on a drill can produce hairlines that are parallel to one another. These can be distinguished from die polishing because they remove surface metal leaving incuse striations where die polishing lines would be raised on the coin. The whizzing process will make a coin look shiny, but it destroys the luster. Luster is created by the (surface) flow lines of the metal when the coin is struck and the metal moves outward toward the rim. Whizzing removes the flow lines.</p><p><br /></p><p>Chris[/QUOTE]</p><p><br /></p>
