As Spinaker, and other lovers of Blue copper know, it's very hard to capture the magentas and blues on a copper canvas. This is better, but it still doesn't quite capture the 'brightness' of the blue.....
ANGLED GLASS
ANGLED CAMERA
The obverse has slightly more intense blue than the reverse. The actual intensity of the colors is somewhere between these two. The difficulty is picking up the colors against the highly reflective fields......there must be a balance somewhere, eh?
Cheers,
Mac

Not stupid at all......
With the light (OTT Light in this case) positioned as shown, the photo is taken with the camera pointed directly down on the coin, i.e., no distortion of the round coin.
This technique was mentioned on the Lightside
Now that I have learned a few more tips/tricks with Photoshop though, I believe that it's best to shoot elliptically (preferably a raw coin) and then stretch the short axis of the coin back to 1:1, and go from there.....but, the Angled technique does allow for better surface presentation from the standpoint of light/dark areas.
Come on over ... to The Dark Side!

<< <i>Have you ever tried the glass method with a slabbed coin? >>
Yes, with varying results. The biggest problem it picking up too much glare from the light source(s) bouncing across the top clear plastic substrate. You can attempt to adjust the brightness-contrast ratios, but not always to good effect.
The other problem with slabs, moreso with NGC, is the coin is often tilted in the white rubber holder (which causes shadowing problems). You also have the inner white wall to contend with.....so, it's really highly variable from coin to coin.
Ahhhhh, the frustration!!!
