That's one of the little side projects I'm working on right now. Whether polymer clays mixed with organics or white clay mixed with acrylic powders and other components. Right now I have the mold made, but I'm waiting on the electrode to be made that will etch the design onto the mold surface.
The compression mold is of stainless steel and consists of two removable cups that possess an outer housing that is equipped with thermal-resistance elements which can heat the mold, if needed (depending on the clay), using a Variac (variable transformer) and a thermocouple to measure the temp.
For the experimental stage with this single chip mold, I will purchase a 20 ton hydraulic shop press to provide more than enough pressure for the chips. For the edge spots, small perforation tools for each edge spot type will have to be made.
For inlays, you would need a printer, a small office/school laminator suitable for polycarbonate lamination and a small office die cutting machine to later cut out your inlays.
I'm guessing the cost would be around $3000 USD, but much, much more if you have multiple molds, seeing as making one chip at a time would be a slow, painstaking process, especially since polymer clay like FIMO needs to be heated to 230 ºF for 30 mins to set.
Anyways.. No promises on anything. We'll just see what happens, little by little, whenever I get spare time.
