<p>[QUOTE=&quot;John Burgess, post: 7932939, member: 105098&quot;]Striations or lines on coins, in the broadest sense, are an error, however there are added value errors, and no added value errors, and this really depends on if there is a demand for it or not in the collector community.</p><p><br /></p><p>Planchet striations would technically be a pre-strike error in the planchet making process, that doesn&#039;t get wiped out in the strike.&nbsp; this has happened many times over the years and I can&#039;t think of a single instance that it adds value to a coin or decreases the value either. Morgans with Striations don&#039;t gain value either I&#039;ve seen them going back to 1880s. just not something that collectors are willing to pay a premium for.</p><p><br /></p><p>The coin is struck weaker than the one without the lines on it, you can tell this from the girls hair and the sleeve wrinkles, it&#039;s still and acceptable strike, just weaker than the one that doesn&#039;t have the striations on it. I&#039;d agree with [USER=23806]@playpossum0985[/USER] that the roller froze and the coining sheet squealed through the rollers and the strike wasn&#039;t quite strong enough to obliterate the lines left behind.</p><p>As far as the color here, I&#039;ve also found them in grey color, always somewhat darker than one without them, not sure if it&#039;s got to do with the temp, or if they lube the sheet up to get it out of there and nobody rinses it off and it gets struck into the blanks when the coin is minted.</p><p><br /></p><p>I don&#039;t think it&#039;s got to do with annealing though. something happens in the planchet making process to cause the lines, light grease might be the surface contaminant, even to cause the weaker strike possibly, and then the strike doesn&#039;t get rid of the lines totally.</p><p><br /></p><p>from my experience, which isn&#039;t much, annealing errors (on clad quarters) tend to look like some variation of this, color can vary by how the annealing process error occurred and the material of the coin (like mostly nickel, or clad) , I&#039;m no expert though. I just know I found it in a solid roll of 2019 AMP in 2019 when I was looking for Ws and came across the two boxes of AMP Ps.</p><p><br /></p><p>[ATTACH=full]1371964[/ATTACH] [ATTACH=full]1371965[/ATTACH] [ATTACH=full]1371966[/ATTACH]</p><p><br /></p><p>which reminds me, I should revisit this coin and get some better pictures.</p><p><br /></p><p>Here&#039;s a cent with Striations also, only example I have so I&#039;ve you&#039;ve seen it before, apologies, been a while since I&#039;ve taken pictures of anything new. it way too uniform to be linear plating bubbles and same direction obverse and reverse on the flip and runs through fields and devices. maybe there are some linear plating bubbles also in the mix.&nbsp; Seems to be a strong strike though.. Not sure why they are still visible unless it was severe and on the zinc core before plating possibly? </p><p><br /></p><p>[ATTACH=full]1371968[/ATTACH] [ATTACH=full]1371969[/ATTACH][/QUOTE]</p><p><br /></p>
