This is the homemade box that I use.
The camera is a Sony e-lens with a long tele and some extension rings to be able to focus close. The lights are IKEA. The copystand is a recent addition from eBay and I am delighted with it...
Despite recommendations to the contrary, you may want to give axial lighting a go. I've built a small box and been playing around. So far I've found that a combination of one light source doing the axial thing + another one on top you can get quite nice results, specially with bronze/ copper. I attach a couple of examples:
Some recent additions, I do like the Half crown and the Groat looks much better in hand. Again none really qualify for coin of the week but the Groat means 1 more box ticked for now. The shilling is currently in a dodgy NNC slab but I intend to break it out ASAP.
