<p>[QUOTE=&quot;cpm9ball, post: 2425636, member: 24633&quot;]This isn&#039;t always true. Have you ever tried holding a coin, any coin, in place with your finger while a grinder is running?</p><p><br /></p><p>Once blanks are cut from a roll, the first step is to run it through the upsetting mill. This is where the upturned edge (rim) is formed to facilitate the metal flow during the striking process. You will note that the rim has been ground away on your coin. This is the first indication that the coin has been damaged after it left the Mint.</p><p><br /></p><p>Chris[/QUOTE]</p><p><br /></p>
