The only power the Constitution gave to the federal government regarding money was to coin it and borrow it. The power to print it is nowhere mentioned.
Furthermore we are faced with the fact that the Constitution forbids the states to make anything but gold and silver coin a tender in payment of debts. If we respect this mandate, how can we possibly believe that the federal government has the power to compel them to use anything else? To believe that the federal government has the right to compel the states to violate the Constitution is against all reason.
I believe in honest money, the gold and silver coinage of the Constitution, and a circulating medium convertible into such money without loss. I regard it as a flagrant violation of the explicit provisions of the Constitution for the federal government to make it a criminal offense to use gold or silver as legal tender or to issue irredeemable paper money.
