<p>[QUOTE=&quot;Kirkuleez, post: 3158684, member: 36864&quot;]So I’m sitting here donating platelets for the troops and finally had time to read this entire thread.&nbsp; There were several LOL moments, some WTH moments, and some just plain say what moments. For me, I always followed Doug’s definition, with the exception of the mechanical rotary bush to be made of metal specifically, but otherwise the coin needed to show some metal buildup at the divices. This is what I had always known and read, and the reason that I initially questioned the grade the NGC gave the half cent that I posted earlier. The definition of whizzing has clearly changed over time, though I wish it hadn’t. It seems that the whizzing term now applies to any use of a small mechanical rotary brush used to make a coin appear less flawed or more brilliant. I can’t say that I like the new definition, but I can understand why it has evolved over time. We have a large machine shop at my work and we use everything from diamond wheels to sandwiched cotton cloth to plastic wheels to polish flaws out of hardened exotic metals like hastelloy, elgiloy, inconnel, 17-4 and titanium to an accuracy of a one hundred thousandth of an inch. New materials and technologies are going to make detecting whizzing very difficult in the near future unfortunately.[/QUOTE]</p><p><br /></p>
