Some call it a Woody . Actually it's a improper alloy mix I've been told . Look it up .Improper Alloy Mix (error-ref.com)
Edit: Actually, this is a woodie. My bad. It's hard for me to tell the difference between roller marks and a woodie, but these are not even like you would see in roller marks, so yup: Improper Alloy Mix. Nice example.
not trying to step on anyones toes of course but they are roller marks/roller lines. the go to call every time one of these pops up is "woodie", and I get it, but it just isn't. there's a good small article about them on it here (I know it's an odd website for this type of thing, it's a lawfirm site, but trust me) https://www.vosslawfirm.com/library/coin-fraud-article-roller-marks-on-morgan-dollars.cfm it's definitely not a woodie, those lines are way to straight and parallel to be an improper mixing of the alloy, it's way too uniform and consistent for a bad alloy mix. not only that, but I've seen quite a few 1980s with these lines myself and even on this site and other coin sites, here's a few more, these aren't my coins or pictures though. not sure who's they are. there are many examples for 1980 and 1980D My guess is the rolling machine to bring the planchets to spec thickness had really worn out rollers that needed replacing that year. In all examples, those lines are way too straight and parallel and uniform with each other to be an improper alloy mix which will depend heavily on how the alloy cools as to how it appears when it tones. roller lines = quite uniform and consistent lines improper alloy mix = usually very random in appearance. sometime wood grained, sometimes blotchy, it's inconsistent from coin to coin. I'm sure I could find more if I keep digging, like I said there's a lot of them for 1980, the only difference is the direction of the lines but that's due to them being struck however it laid in the press at the time, the lines would all technically be in the same direction on the coining sheet as it was brought to spec thickness until it's punched out and then struck in different directions.
I can't see roller marks going right up to the arches or other raised parts. so i think improper mix also. IMO, Jim
Ignorance is Bliss! I have no dog in this fight since I've never looked into it. Based solely on the link you provide, it says... "Roller marks are parallel incuse lines that are formed on the metal surface of the coin during processing at the Mint." "If any tiny little piece of stray matter gets onto the ingot or the rollers, (such as little shavings of metal, or dirt or sand,) the incredible pressure from the force exerted by the rollers will cause the foreign matter to carve fine lines or grooves into the sheet of coin metal." "Long, Straight, and Parallel Lines - There are a few other events which can happen in the mint that will cause similar looking damage to the coin planchet, but roller lines can be distinguished from these other types of damage by the fact that roller lines are straight and parallel." "Another diagnostic for confirming roller marks are that they will go underneath (and sometimes across) the devices on the coin and continue on the other side." "when the coin is struck the lines are usually obliterated by the devices rising from the surface of the planchet during striking. The roller marks on the field area of the coin are often still present because the force of the strike wasn't enough to obliterate them. Large coins are more difficult to strike well, which is why roller marks are far more common on large coins such as Silver Dollars, than they are on smaller coins like Seated Dimes." This is what I get from the article... 1. Roller lines are incused. 2. Roller lines are more likely seen on fields than on devices, but not always. 3. Roller lines are more common on larger coins. I'm hearing arguments for/against these being roller lines...but likely roller lines. Either way, they're both Mint errors. Does this help?
What changed my mind from roller lines was that I thought one of the requirements for roller lines is that they're not only straight but even and consistent. As you can see, these lines vary in width. The dark (blue arrows) goes from wide to narrow as well as the light (green arrows) from wide to narrow.
Sorry guys I didn't see your comments til late ......but Lincoln wasn't being very photogenic. Still learning I appreciate all of your help
is it or not who knows all we can do is guess, since we weren't there when the coin was minted or inspected the copper for other alloys
