From the Coin Community Glossary:
whizzing
Term to describe the process of mechanically moving the metal of a lightly circulated coin to simulate luster. Usually accomplished by using a wire brush attachment on a high-speed drill.

1935S and 1936 - harshlyt, cleaned
1937D - This one looks OK
On the first two I see no indication of cartwheel luster. When photographed you can usually see the "wheel spokes" on a cartwheeling coin. I think I see a couple spokes on the reverse of the last coin.

Thanks for the info, KenKat. Seems that an operation like that would leave marks.
Maybe they were cleaned with a metal polish such as Maas?

If they're all from the same seller I'd say their all suspect.
I don't think they are with original surfaces, but I agree the 37-d
has the best chance of being OK and is a nice coin. They all have a flat
look to them.

Tried to image two of them to show cartwheel. Sorry for the blur. I can see it when I tilt them.   |

The first pic of the 37-d looks like it has some bubbling around the neck and the back side of his lower head. Not much but it does stand out to me. On the reverse of the one it looks like something that was sprayed on is or has flaked off in the one spot.

Whizzing doesn't leave marks because it is a rotary or circular method that simulates the circular flow lines that are created during the minting process. That's how you can get the luster effect.
What you do get from whizzing is a metal build up around raised surfaces of the coin.
Whizzed coins can be attractive and I personally find them really difficult to identify although I am trying to learn.
In the picture of the 37-D above, it just makes me suspicious because the details seem a little mushy - like around Lincoln's chin and nose - and there seems to be some kind of shiny ridge running up his back that might be residue from whizzing.
It just looks a little off to me but it could just be the picture or I may be dead wrong about detecting whizzed coins. In fact, I'd say there's probably a pretty good chance I have a couple of whizzed coins in my collection. Like I said, I find it really challenging to detect.

The thing that stands out for me is all the bag marks look softened.
I can replicate this look on a coin by putting them in the tumbler with 9000 grit platinum polish after a quick acid dip. I have done this to restore badly damaged coins stuck in asphalt or blackened from fire.
FYI 9000-12000 grit is roughly a half a micron, you won't be seeing the trace evidence with a loupe.
