1885 Morgan Dollar Pl?

Whoa.

I'm going to go out on a limb here, and say that your last three images pretty much tell the story. Yes, this is easily PL, and possibly DMPL. You can't fake that kind of mirror.

However, the lines you mention could be the result of brushing/polishing outside the Mint, or they could be die polishing lines done by the Mint. Here's a rule of thumb: if they're die polishing, you will see them continue (and maybe even be heavier) at the intersections between fields and devices. If it's postmint brushing, those lines will likely cease before they intersect the devices - if you think about it, you'll visualize how brush bristles won't easily hit that tight space. And if they've brushed it hard enough to fill that gap, you will easily see the lines continue onto the devices.

That's just for instruction; your last three images - mirror finish in the fields, frost on the devices - make me 98% sure you have a nice Prooflike 1885. They are not uncommon that year, so I find it easy to believe.

Lovely coin.

need better pics but possibly even DMPL

I really don't see much for scratches in your image. If true Mint die polishing, they will likely (but not certainly) be vertical (up and down as the coin is oriented the way it is in the pic) and pretty numerous.

They did this, sometimes, during the striking life of a die to "refresh" it. The result of such polishing was a die which as again capable of striking a few PL and DMPL coins, just like you'd expect it to when brand-new. A plainly-polished yet PL coin is, in fact, likely the result of a "refreshed" die. That's because brand-new dies were subjected to the basining process - ground against a revolving circular and slightly conical disk, to impart a very slight convexity to the die. This aided metal flow into the periphery of the coin during the strike; occasionally they overdid it a bit, resulting in coins like the 1878-P VAM-14.4, known for its' concave surface.

Basining was a pretty precise process, resulting in a very smooth die surface after which the die was not further polished, whereas die polishing was done by hand and even though it created dies capable of striking PL's, it resulted in hairlines on the coin.

Yes. Remember, dies were negative, so the coin could be a positive. Therefore, the polishing process resulted in the polishing tool "dropping off" the edge of a device - much the same force as deburring the edge of a metal piece - so you can see how you'd see those lines heavier at the edge of a device. But they won't run into the device itself.

Looks like a mishandled DMPL.

To expand a little on D0ubl3Eagle's accurate words, we refer to what you've circled as "chatter" in the fields. An unavoidable consequence of the coin bouncing around a bit in a Mint bag.
