The federal reserve dollar is not an American Dollar. In fact America can only issue currency in the form of gold and silver. The federal reserve, a private institution issues "The Federal Reserve" dollar as a private currency enforced as payment of debt unconstitutionally.

18USC334 makes it a federal felony to issue Federal Reserve Notes without complying with all provisions of law
12USC411 requires the Federal Reserve to redeem FRNs in "lawful money" on demand
