You should try putting an old coin under you microscope.

Dude, you actually may have something.

Why is it impossible for you to show a photo of the whole coin showing the circles?

Why do you not reply?

We do not need 5000 photos of coin magnified 100X

We do need a clear photo of the whole coin, why is that so hard?

Gosh Golly, the lighting and image rep given off between a hand held magnifier under a lamp, and my microscope really need to be hashed out by me

There was nothing different when I manually looked under the light with my hand held. They all crossed the threshold

Last try, then I am out.

Here is a photo of my coin with concentric circles.

Please show your so called error coins as a whole coin image.

Those ones in the Lincoln Memorial are crop circles done by microscopic extraterrestrials

Here's an interesting link to a 2011 concentric lathe line conversation from this forum.
