That headline is a direct quote from J.P. Morgan.

He was and is right. When you hold a twenty dollar note in your hand, it isn’t money. As it says right at the top of the face of the bill, it’s a Federal Reserve Note. It’s simply a note from the Federal Reserve that promises a value of $20 to whomever you give the note to. It has no inherent value.

A gold coin, or gold bar, however, does have an inherent value. It isn’t the promise of money, it’s the real thing
