<p>[QUOTE=&quot;yakpoo, post: 1257544, member: 18157&quot;]I was looking for information about the laser technique the Mint uses to produce frosted devices on US proof coins and I found a few items that may be of interest. </p><p><br /></p><p>I assume the frosting (texturing) is applied to the die, not the coin. Does anyone know how this texturing stands up to the minting process? In other words, how often is a die &quot;textured&quot; and do early strikes differ noticeably from later ones?</p><p><br /></p><p><b><a href="http://foba.de/fileadmin/Downloads/FOBA_Mint_Brochure_GB.pdf" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://foba.de/fileadmin/Downloads/FOBA_Mint_Brochure_GB.pdf" rel="nofollow">A brochure from the FOBA company</a></b> A company that makes laser marking and engraving machinery...frosting and surface texturing being one of the steps.
