During World War 2, the British designed a machine gun that could be easily built by anyone with access to a basic metal shop. The result was the Sten gun, which was produced in relatively large numbers in occupied Europe. Similarly, the Liberator could be easily mass produced and was intended to be used by the people of occupied countries. Both of these products worked on a massively distributed basis.

We can use the same idea for producing a currency. By creating the design and allowing others to actually produce the currency, we can decentralize it so there is no "head" to cut off.

Apparently, a minting press can be constructed from small hydraulic devices like car jacks or wood splitters. Anyone with a die set and a hydraulic press can mint their own silver pieces.
