<p>[QUOTE=&quot;Conder101, post: 6488206, member: 66&quot;]You reduce the thickness slightly. By 1.5%&nbsp; If a Morgan or Peace dollar blank was say 2.5 mm in thickness, you reduce that by .04 mm and you&#039;re there.&nbsp; It won&#039;t be visually different, and it won&#039;t be detectable on the finished struck coin either.</p><p><br /></p><p>Typically coins are specified by weight, diameter, and composition.&nbsp; The thickness isn&#039;t specified because once you have the first three the thickness becomes automatic.&nbsp; And that determines the thickness of the blank not the coin.&nbsp; The thickness of the final coin is somewhat determined by the force of the strike, especially since most people measure the thickness at the rim and the stronger the strike the more the rim fills.[/QUOTE]</p><p><br /></p>
