They do. NORFED (the organization that makes Liberty Dollars) goes out of its way on its website and in its literature to make it clear to the consumer that these coins are NOT LEGAL TENDER. You can’t pay your taxes with them, you can’t make court settlements with them, and you can’t compel merchants to accept them if they don’t want to. They are just plain old little chunks of gold, and we should be free to trade them about as much or as little as we want.
Then they ought to have their lawyers investigate how exactly they are advertising differently from the Franklin Mint, which doesn’t get charged with money laundering and wire fraud, etc.
