Can the bank change a dollar bill?

Of course. If you need a lot of one-dollar bills, you'd better make an appointment with the bank in advance, tell the bank the number of one-dollar bills you need, and then go through the exchange formalities at the bank counter the next day with your personal identification. Ordinary commercial banks can handle this business. Do it before bank hours. If it is handled on weekends or holidays, you need to ask in advance which branch of the bank is working normally. According to the regulations, banks can provide free money exchange services for everyone. If there are not many banknotes to be exchanged, you can go directly to the bank to get the number, and then queue up to get the number. If you find it troublesome to change paper money at the bank, you can also choose some small supermarkets nearby. Under normal circumstances, as long as the number of changes is not too much, business owners are still willing to help.

With the development of commodity exchange, money appeared. At first, money was served by some recognized equivalents, such as shells.
