Newbieee,
I agree with a bad cleaning job. Milestone coming up, contest coming up?

Ive tilted it under a scope and loupe and they do not seem to be into the coin.. there are a few hairlines on it that have the normal shine but these show up differently. Gave it a long soak in acetone also cause it looks like it is glazed or something but nothing came off. These lines don't show nor shine with the naked eye even tilting under light. When I first got into morgans years ago I thought it was cleaned and put it in the cull case but now I'm not sure. This photo shows what it looks like in hand better, I had lighting at a certain angle and tilted the coin earlier to show the lines I described.

There is not cartwheel but I think its because it reflects the light everywhere

I thought so too at once but when I went back through these just something about the details drew me to look at it again. Have a dozen cleaned ones to compare to and it just doesn't fit the bill. There's no luster even around the edges of the letters or inside of the hair as if the whole thing is a mirror.

Polishing a coin will give it a mirror-like finish without cartwheel luster.

Thats why I gave it a over night acetone bath since
that was what I thought when I noticed the lines weren't into the coin but absolutely nothing changed. Seems like an overnight soak would at least remove enough polish to change the orientation of the lines but it came back out glossy like before and lines the same way. There's something different about this coin

Also the lines are much wider than cleaning lines, like polish lines that were squeezed almost flat and were widened in the process which I assumed would be planchet polish lines

Die polish lines are raised above the surface. Scratches, and cleaning lines are below the surface. Planchet striations are flaws in the planchet that are not removed from the coin when struck and the striation are below the surface. Put the coin under light and tilt it back and forth if the lines change directions the lines are cleaning lines. From the photos the lines appear to be caused from a scrape on a hard surface. Die polish lines would be on the fields, but not on the cheek. Unlikely that planchet striations would show up on both the cheek and field as these two areas are under different metal flow pressure when the coin is struck.

The overnight soak was referring to if it was polished post mint. I had to do another one a while back and things looked different after I removed polish. Ok thats good to know thank you. These lines don't move under light. I just had to put a bright light on it to even see them without magnification.

Polishing a coin is not like waxing a car. There is no residue left on a coin after it's been polished, so a soak in acetone wouldn't affect it.

Below is a photo of planchet striations. These striations were made from the sheet of silver metal being moved along with rollers. These striations are referred to as roller marks. Note on this coin that the roller marks stop at the cheek and do not go into the field.

This Coin is cleaned, there's no polish lines here.
