Take a look at my post in the Classic coins forum:
https://goccf.com/t/47485All photos use a Canon Rebel XTI (10MP) camera with Tokina 100mm Macro.
For the flashy Proof photos, I used a copystand with a 75W incadescent bulb (with diffusing paper) pointing into a reflective glass setup to shine light onto the coin indirectly.
The flat light type pictures use a standard 60W bulb in a lamp the did not directly shine onto the coin but just provided ambient lighting. I used a tripod for these pictures.
