<p>[QUOTE=&quot;Pickin and Grinin, post: 26052215, member: 73995&quot;]Your OK, roller lines are usually fully deleted in the striking process, They, are usually found on CuNI coinage because NI is a very hard metal and it will damage the rollers when the ingots are forced down to correct thickness. Coins with roller marks usually are premium planchets, they show a very smooth surface free of major voids and defects. The lines are near perfectly parallel. </p><p>Improperly mixed alloys are a bad mixture of the metals resulting in a streaky/grainy coin that kind of reminds you of a piece of wood, commonly called a &quot;Woodie&quot;. These planchets have voids in the ingot because the metals did not mix thoroughly. They are more likely to have a void or loss of lamination.</p><p>It is why I think that your coin is an Improperly mixed alloy rather than having anything to do with striations or roller marks.</p><p>I am not saying it is damage but.</p><p>Loss of laminations or unstruck areas/voids in a planchet do show a luster.[/QUOTE]</p><p><br /></p>
