You will be surprised! Public Law 94-564 placed a significant amount of gold into the IMF Trust Fund (United Nations). This founds the system of the Fed Asset SDR's - Special Drawing Rights. If you Search for "Fed Assets Current" you will see the latest asset report and if you read it in context of PL-94-564 you will slowly clear a fog about "Fiat" and "Gold-based Currency". Many folks who only study this halfway through say that US notes are gold-based while they say Federal Reserve notes are fiat currency. This misnomer is inconsequential regarding your lawful money refund so I do not insist on correcting the misperception. But it is the opposite in truth. US notes, invented in the 1860's are a complete trust in government to redeem the notes while Federal Reserve notes, like in the Fed's Asset Report actually have the gold you forfeited, now held in trust - your credit granted by endorsement - for backing.But mostly, FRN's are backed by endorsers pledging their estates as a mortgage to the US Government. It is ignorance of your transaction (endorsement is a naked contract) that makes the difference of night and day. So it is helpful to keep this in mind and come back to it after redemption solves conditioning between your ears!
