US Presidency
1860

It is invested with the power to coin money and to regulate the value thereof, and to regulate commerce with foreign nations and among the several States. It is not necessary to enumerate the other high powers which have been conferred upon the Federal Government. In order to carry the enumerated powers into effect, Congress possesses the exclusive right to lay and collect duties on imports, and, in common with the States, to lay and collect all other taxes. But the Constitution has not only conferred these high powers upon Congress, but it has adopted effectual means to restrain the States from interfering with their exercise. For that purpose it has in strong prohibitory language expressly declared that No State shall enter into any treaty, alliance, or confederation; grant letters of marque and reprisal; coin money; emit bills of credit; make anything but gold and silver coin a tender in payment of debts; pass any bill of attainder, ex post facto law, or law impairing the obligation of contracts.
