Hello From Anza California - 1917 Lincoln Severe De-Lamination

You can post the new pictures on here! even if you did not save them in your pics. file you can copy,save them again then post them on here,that is the policy of the site to continue the topic in its original thread and not to post a duplicate thread.
I forgot why I came here in the first place I am skeptical of being anything other than a glue type residue, what is the weight?although not always successful to remove the glue, but have you tried to soak it in the pure acetone?

I originally posted this in the Introduce yourself area. It was my first post. I was asked for better photos. I purchased a Chinese Digital Microscope from WISH for $15.00. I was able to get some very good photos with the Scope. Maybe now someone can identify exactly what is going on with this coin.
I do want to make one thing clear, these marks are NOT residue, They are NOT embedded hair or other foreign items. These are cracks into the surface of the coin. If you look at the edge shots you can see the cracks extend deeply into the coins surface, and appear that you could actually pry the layers apart.
Any ideas or other examples would be appreciated.

If this was a struck-through-thread error, then the impressions of the threads should weaken where they cross heavily worn parts of the design, like the wheat ears. They do not. Instead, I suspect that these wavy lines mark the edges of areas that are acid-etched. I do note that the surface texture changes on one side of the line, with the slightly rougher texture being the area that was chemically etched.

I think it's a delam. I mean come on, looks like it's gonna crumble apart.
