Very nice clear example of a RPM. I think that it is listed here on varietyvista, but you should check for the confirmatory die cracks:

that is a nice resource; I didn't realize this coin had been studied that deeply.

I have no evidence of the die crack. As best as I understand the site and page, that means stage A.

The cheap microscope cam lacks the field of view to get anything bigger than a small cent.
I scanned it, that does OK but the lighting is what it is.
The I of IGWT is flat. There are a few other little nicks and scratches. All in all though its in pretty good shape for what it probably is (most likely a pulled from change early in life coin).

What might help for lighting your image is to get the light source a bit more over coin. With the light reflecting off the edge of the bust, it tells me the light is too low.

You might need a light source that might bring the light more in where you need it?

I use this type of light on my scopes in the past:

Thanks for that!
ATM I have a document scanner (the full coin shots) which has no control, it does what it does. Its not ideal. And I have a microscope with a light at the lens that provides bright straight on light or I can turn that off and wave a bright LED flashlight at it until I am happy with it (practice makes perfect here). I don't have a true camera or camera phone etc. One thing at a time, the microscope is new, and next I will get something set up for normal images. I wanted a way to get the details out for now. I am not a big spender on the hobby.

I can do image enhancement algorithms but I have not done that in a few years, need to see if I can find my old code and not sure if I even need it.
