<p>[QUOTE=&quot;Insider, post: 2714934, member: 24314&quot;]Doug wonders: &quot;The one thing I&#039;m still wondering about, on Insider&#039;s coin, the uniformity of the depth and width of all the grooves left behind by the acid - that one I still haven&#039;t visualized. I mean ya just wouldn&#039;t expect that all hunks, chunks, streaks of impurities would all be of the same thickness and width. Some of them would almost have to be wider than others and thicker than others. But that is not what we see when we look at certain areas on that coin.&quot;</p><p><br /></p><p>The etching is as all different depths, directions, and sizes.[/QUOTE]</p><p><br /></p>
