Do Die Polish Marks Resemble A Light Circular Motion Cleaning?

RCDB

I was going through some coins to choose my second group of submissions and came across something I hadn't seen previously on a very nicely album toned MS65 Morgan. There seems to be a small set of circular lines that go around most of the coin, both obverse and reverse beneath the toning. I did not notice this when I purchase it, but I'm using more magnification now and these lines are very clear. They are totally circular, never straying once from that pattern and exist only in the fields of the coin. Never once do the lines straighten, nor do they ever touch the eagle or portrait. I wouldn't say they look like scratches. They look like a circular spider web. I believe this coin is at least prooflike beneath the toning and now wonder if someone cleaned the coin previous to placing it in an album. That wouldn't seem to make sense, but at this point I am not certain what to think.
Your opinions please.

Also, if they are die polish marks, how will NGC or PCGS react to them. Will they grade the coin? Could the coin be downgraded? Thanks for your thoughts.

Look at the lines carefully. If they are raised from the field then it is die polishing. Inward scratches on the die would make raised lines when the coin was struck. Hairlines from cleaning will be inward scratches on the coin.

No, circular would be cleaning!

Then again, maybe I just have'nt seen any circular die polish lines. Look closer like jom says, I would suspect cleaning to hit the devices also.

Die polish lines, aka striations, are not circular.

Could they be from the die cutting lathe, like we've seen on some IHC's?

Could the coin have been whizzed?

Die polish lines are almost always straight lines that will stop at one side of a device and start right back up again on the other side without affecting the detail of the raised device. This Kennedy Half shows die polish lines around the date and lettering as well as around the eagles tail on the reverse. It is also a rotated die error coin with the dies in Medal Alignment which means it is probably one of the first few coins struck from a freshly polished die.

Mercury dimes have circular die polish marks, so they could be on Morgans, too.

Die polishing lines can come in all shapes and sizes it just all depends on how you use the grinder. mike

These marks are not raised. They are definitely marks into the fields of the coin. If die polish marks are raised, this is a cleaning.
