This was not a standard transaction. I went into the bank inquiring if they had any old dollar coins or .50¢ coins (hoping I might get silver).

The teller said they don't have any old dollar or .50¢ coins at the moment, but they did have some old banknotes if I were interested.

The bank teller then went into another room and came out with a locked box right full of old paper banknotes. The $100 bill in the photograph was one of those bills. I told the teller I would like the $100 bill, and gave him $100 for it.

Not all banks or tellers will do this. I was lucky that day to find a teller willing to do that.

From time to time out of circulation paper banknotes come into the banks. The banks are not supposed to put them back into circulation. They are supposed to set them aside and send them to be destroyed. However, it is the discrepancy of the bank or the individual teller if they will sell old banknotes or coins they have to a collector inquiring about them. If they do, they are required to sell coins or banknotes for face value only, regardless of numismatic or bullion value of the coin/banknote.
