I gave a store an old Twenty dollar bill. And they said they could accept it. I explained it was still good. They said they knew. But it was against their policy. Actually, all U.S. paper money is always legal tender and acceptable for exchange. I was reading up a little on paper money about 20 years ago. And every dollar bill that has been issued since United States notes were introduced in 1862 are good. And this includes gold and silver certificates too. They are now worth their face value, even though the federal government will no longer give you gold or silver for them. Actually, the man was wrong because as it says on each dollar "This note is legal tender for all debts, public and private" meaning every business has to accept them. Even an old greeback dating back to Abraham Lincoln's time. (I think he said there machines just didn't accept them anymore.) It's interesting, because all U.S. currency will always be face value. But you would be foolish to use them in a store. Because a collector will pay many times their face value for them now.
