As far as manufacturing ease would go it would be easiest to take a solid block of plastic and rout out the spiral design through the bottom first. Then rout out the thickness of the silver insert and then chamfer the ends of the hole and the silver. epoxy the silver in place and clamping pressure will keep it from ever coming loose. A two piece design. I think I've seen a few "coin blocks" like that but not sure how the guts were designed in them.
