Clearly it is new currency distinguishable from the old, and if they can't be exchanged as has been contended:

This happens every year for American government, no matter if new design or not. As old bills return to banks, they are exchanged by government for new bills. You cannot ask for old bill.

It seems a further restriction on our ability to take our cash where we wish and spend it as we wish.

Existing bills will be legal for use in America for ever. I do not understand concern.

The article was not clear on this point (perhaps the book/mongraph is) but it would seem to imply the Treasury would print and maintain two sets of currencies - a domestic (new design) and a foreign (old design) US bill set (the old/exising design) but the two would not be exchangable. Worn-out new-design domestic bills could not be exchnaged for old design bills and worn-out old design foreign bills could not be exchanged for new-design domestic bills.

See agitator's post #8 for some hints at prior attempts in congress to establish a dual currency system.

It's hard to understand the ramblings of a paranoid person. It's a form of mild mental illness in most cases.

"Existing bills will be legal for use in America for ever."

Historically that is not true. Try using a 1928 gold certificate or a Federal Reserve Bank Note. Currency can be invalidated or declared illegal at the whim of the government. Remember FDR and gold during the Great Depression?
