Final Setup Help

On your 2013 the lights look like they are a bit too low an angle. See how Lincoln's forehead is "outlined" with highlights, as is his nose, beard, and back. Bring your lights higher and you'll get less reflection off the edges of the devices and more on the surfaces. Brighter surfaces will allow you to lower the exposure and this knocks the highlights down.

The biggest problem this image has is the white balance. It's far too red. There are also odd highlights on the bottom edges of the features. Overall the image is good, with good exposure and focus. I don't see much blurriness anywhere. I took the liberty of adjusting the color balance, levels (contrast and brightness), added bit of sharpness, and added some pointers to the highlights of concern I mention above.

It may be that you have a light on in the room that is shining toward the coin and causing these highlights. Try moving your hand around the coin when in Live view and see if the highlights disappear.

Those shadows look fine, and are needed for the coin to look natural. Don't try to get rid of all the shadows, just make them as uniform around the devices as you can. A "proper" image covers the entire dynamic range of light intensity from blacks to whites. Your image above does not push shadows to black. If you adjust levels so it does, it looks like this:
