You would not be able to put “dollar” on the coin or would get in trouble by FBI/Secret Service like how NORFED ran into problems
The Hobbyist Act, I believe, would allow anyone to legally make such a coin. It’s the same law that allows someone to overstrike a U.S. coin. I can certainly see your point, though. It probably screams competition to the dollar and the Feds. That's kind of a joke, though, unless one were capable of minting millions of these coins to actually compete with the dollar (along with some other reasons). To my knowledge, the guy who created Norfeds and got into all that trouble won the main cases against the government. It was a pivotal time. Around the same time, Mike Caldwell shut down operations while the Norfed guy was fighting the government tooth and nail.
