Hello Arminius,
Thankyou very much for helping to identify the mint and moneyer, very much appreciated, it had me baffled for a while!
I use a homemade axial lighting system, similar to this - http://bit.ly/2sxH12r but a little more honed for coin photography. I use a dark background which is tidied up afterwards with a photo editor, it works very well.
Kind regards
