you can get shapeways to make you a headbadge out of brass, bronze, silver, gold plated brass, or platinum. they 3d print the design and then cast it in metal.
I have been wondering how hard it is to go to the company that Chapman uses, it's a local RI company that makes badges of all kinds. It's Hook-fast

I doubt that a one-off is economic to get from them though, somebody try it and tell us.
