I don't understand what you mean. They removed the paper money the explicit said "this is good for one silver dollar and can be exchanged at the US Mint at any time" (those were called "Silver Certificates" and look a lot like the dollar bills around nowadays, without the promise. Now it says "backed by the faith and credit of the US government" (or similar) ....so "backed by a bunch of hot air" basically. HUGE DIFFERENCE.
