When President John Fitzgerald Kennedy - the author of Profiles in Courage -signed this Order, it returned to the federal government, specifically the Treasury Department, the Constitutional power to create and issue currency -money - without going through the privately owned Federal Reserve Bank. President Kennedy's Executive Order 11110 [the full text is displayed further below] gave the Treasury Department the explicit authority: "to issue silver certificates against any silver bullion, silver, or standard silver dollars in the Treasury." This means that for every ounce of silver in the U.S. Treasury's vault, the government could introduce new money into circulation based on the silver bullion physically held there. As a result, more than $4 billion in United States Notes were brought into circulation in $2 and $5 denominations. $10 and $20 United States Notes were never circulated but were being printed by the Treasury Department when Kennedy was assassinated. It appears obvious that President Kennedy knew the Federal Reserve Notes being used as the purported legal currency were contrary to the Constitution of the United States of America.
"United States Notes" were issued as an interest-free and debt-free currency backed by silver reserves in the U.S. Treasury.
