Minting ain’t what this is about. It’s about recognizing gold and silver as money. Go back and read the Constitution; the States shall recognize nothing but gold and silver as money. It’s already in there, but like everything else, they’ve papered over the Constitution with laws (Federal Reserve Act), and this is an attempt to reverse that.
Or currency backed by gold and silver...which was a slick way to get around gold and silver currency.
Funny thing, those who think US Grant was a real bastard dont read what he did concerning legal tender. Or Andrew Jackson for that matter. Or, several other presidents who declared a national bank unconstitutional, which is the real culprit in these matters.
