Quote from bestfriend:
The only power to coin money or issue legal tender is vested in the federal govenment. The Marianas Islands got in trouble with this.
WRONG!
Read your Constitution. Those islands are not a state. Also, if I recall correctly it grants the Federal government the power to "coin money", not "issue legal tender". Big difference.
The founders lived through the days of "Not worth a Continental", which is why they only allowed for coined money.
BTW, I think it was New Hampshire that was the most recent state to coin money. But anyway, its a losing proposition for any state to coin real money when the Fed is printing paper like confetti that can be used to buy it. There is some saying about "good' money vs "bad" money that explains it.
