Even though it still says FRN, by virtue of the signatories being he himself and the secretary of the treasury, I hereby declare that’s pretty f’in close

A US Treasury dollar isn't just in name only, it's supposed to be tied directly to gold and silver on deposit at the Treasury, that could be freely redeemed at a statutory peg. It's this second part that we're waiting to see, until then FRNs gonna FRN.

It seems no president has every had signatory on our currency before. Not sure if this is just pure symbolism or if there's an underlying current that is hidden from view regarding this...
