Yes, it may be hard to believe but the U.S. government did print $500 dollar bills for the general public at one point in history. This specific $500 dollar bill was printed in 1928 and features a portrait of the twenty- fifth President William McKinley. Today, there are very few of these $500 bills left. Nowadays they are collectors’ items and sell for thousands. The funny thing is that they still could be used in stores today, because by law they are still U.S. currency. If you are interested in buying $500 bills you can find them for sale online.
