1980-D LMC Woody Obverse And Reverse

thanks coop . I think someone on the forum needs to find a mint employee and buddy up to them lol.

Do you mean the darkest line ? I'll have to get it back out and look . Thanks oldmike it's already in a 2x2 .

Roller lines not being visible on the tops of some of the devices is consistent with the roller lines theory because they are only formed on the surface of the coin to begin with. Unfortunately, it's also consistent with the traditional theory that Woodys are caused by improper metal, in which case it may or may not go all the way through the coin. Both theories are logical conjecture.
What we do know.. is there are many old and modern Woodys that only show on part of one side, or all on both sides, or anywhere in between. Woodys can sometimes be found on any denomination of any composition of any coin, including clad and silver coins. The stripes on coins can be wide apart, or close together. They can be evenly or unevenly spaced. They can span the length of the coin or be only part way. They do however, go in the same general direction, and when on both sides, they match up - as the OP's coin does.
I've touched on the theories and the facts, now if there's no objections I'll share my opinion. (pause) None noted, thank you. lol I believe both theories are correct depending on the coin. The wider spaced and sometimes mixed color Woodys look to me like improper metal. This can account for the often accompanying Lamination errors also. The narrower and evenly spaced Woodys look to me like roller lines errors, which is consistent with Mike's theory of improper heat and roller lines. They are often evenly and monochromatically discolored.

I was looking through roll of all copper cents tonight. I pulled a few out that looked like this and ALL of them were 1980D's. Under magnification all 1980D's in the roll had these on one side or another.

I have one that has these same stripes on both sides sitting in acetone right now.

Montcollector you say all of the 1980 D had the same lines ? I'll have to start looking closer at mine. That's cool ! Are they the same as far as spacing and boldness ? Post a pic! thanks spruette I like the way these look I have a ten year old daughter that loves to find one of these she keeps them all regardless of boldness or one or two sided she says they are pretty .

You're not saying you have two of these that are exactly the same are you? If you do, can you post them side by side?

My misunderstanding. That would have been really something. Thanks

Hey folks, still arguing?. I do agree w/coop, why I said roller lines, looking in betwixt columns, where I saw it. Picture this,wish I had my old CAD program...two rollers, side by side revolving in opposite directions, one CCW, the other CW, the belt around one rotates both rollers, space between them is in the microns, way less than 1 mm. Now think what happens when coins go through that space, "going through as wringer" ring a bell? After many years of use,these belts get...DIRTY. Imagine the pressure, doncha jus' tink, something might be "applied" to these coins? Huh, huh!
