<p>[QUOTE=&quot;desertgem, post: 3370306, member: 15199&quot;]Insider, I still can not justify in my mind how a single squeeze hubbing can produce a Doubled Die. Yes, I know the engraving CNC tool &quot;skips , vibrates, or slides&quot; as it does its job and withdraws from the surface. That is a single event ( Die goes down, die comes up) .Why is it a &quot;doubled&quot; as it seems to me like it is MD and should be called at best MHD&nbsp; ( mechanical hubbing damage ) rather than True double (hubbed) die.&nbsp; I know some &quot;companies/people&quot; push these as equivalent to real DD for the income, but you are a professional, I would like to know your opinion and if your company authenticates and slab most of these. I know you are a old timer like myself.&nbsp; If you prefer not to comment, I respect that, Jim[/QUOTE]</p><p><br /></p>
