When did they take the part that says "No state shall...coin money" out of Article I, Section 10?
No State shall enter into any Treaty, Alliance, or Confederation; grant Letters of Marque and Reprisal; coin Money; emit Bills of Credit; make any Thing 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, or grant any Title of Nobility.
This amendment, in fact, says that States must pay back their debts in “gold and silver coin.” How have states been paying back their debts since 1971 (when the nation wnet off the gold standard)? US Dollars? That’s unconstitutional. While you are technically correct, that coining actual currency is not Constitutional, States paying back our debts in silver and gold IS. If States choose to do that, they are merely following the Constitution.
