@Gluggo and TobyJ - you seemed to cover one of my issues on bright/reflective coins. Nice photo's!
I have been playing around with axial light setup.
- Nikon D5200 w/40mm micro lens (macro)
- Old monitor arm adjusted for to fit camera mount
- LED light (3200-5200) adjustable dimmer (1% to 60% depending on coin)
- Picture frame with plexiglass @45' ( Think I should switch to real glass)
- Various mounting hardware and black cloth
- soft box to avoid direct light on coin
- exposure time 0 to 15 sec (depending on coin), ISO 100, manual focus

I was pretty happy with darker/toned coins

This coin has almost an obsidian black tone to it, so color is correct, though I could not get a nice shot of the dime which is a similar color to just inside the rim of the coin.





But the bright red/silver/cameo and reflective surfaces provided issues. Any thoughts on these would be appreciated or should I be using a different setup for these types of coins?



This one should have a nice light/sky blue look to it, instead of this beige'ish red. I tried going to 5200k light and still had a similar result
