<p>[QUOTE="VistaCruiser69, post: 4145769, member: 107016"]Over the past year or so, I've come across quite a few quarters and pennies with these same type of lines on both sides of them. After posting them on this site and getting various responses, I've come to realize that these lines may have something to do with rollers that are feeding the coin material through the minting process or after, (correct me if I'm wrong). I have been shown examples of what coins look like with material mixture issues. Those will look more like wood graining. The coin shown above and all of the ones I've found so far, the lines are very even and straight, unlike the examples that looked more like the wood grain appearance.</p><p> </p><p>Here's an example of the two:</p><p> </p><p><img src="https://imgs.inkfrog.com/pix/coop49/rolling_lines_-_woody_SBS_willburton_coinmasters_AAA.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" />[/QUOTE]</p><p><br /></p>
