<p>[QUOTE=&quot;C Jay, post: 1227448, member: 13184&quot;]I think it has to do with whatever coating they use on the dies to get a burnished finish.&nbsp; I had matching series of specks show up on differnt coins, which would have to be atrributed to the die.&nbsp; Also one coin would show less specks than the other, so I think it is a type of deteriation as the die wears out.&nbsp; Most of these I was only able to detect under a USB microscope, with only one or two of the specks showing in hand.&nbsp; My Grand Canyon look nice in hand but I&#039;ll put it under the scope to check.[/QUOTE]</p><p><br /></p>
