I have a small 20x Bausch & Lomb. I do not think it is very good for coins though. It has a 3 element lens, but it also has a very narrow depth of field. As such it is an excellent glass for looking INSIDE faceted gemstones, in the inspection of inclusions within the stone.
Besides numismatics, I have a nice collection of about 200 or so faceted gemstones, of which I have faceted about 70 myself.
