<p>[QUOTE=&quot;cpm9ball, post: 3033960, member: 24633&quot;]I think you mean &quot;crater effect&quot; which is a term I started using more than 20 years ago to describe the raised metal along the edge of a gouge in a coin. However, it does not apply to this coin because the Mint stopped hand-punching the mintmarks into the working dies in 1990. </p><p><br /></p><p>If you examine any of the mintmark punches that were once used, you will see that there is a flat surface surrounding the letter just like the field of a die which prevents metal from pushing up along the edge when the letter is punched into the die. You can argue this point all you want, but you will be wrong.</p><p><br /></p><p>Chris[/QUOTE]</p><p><br /></p>
