Step 1 : Introduction to the question "Which famous landmark appears on the back of the US $100 bill?"
The $100 bill features a portrait of Benjamin Franklin on the front of the note and an image of Philadelphia’s Independence Hall on the back of the note. If you have an eye for detail, you might have noticed that the time on Independence Hall’s bell tower clock on the back of the old $100 bill read 4:10. It was changed to 10:30, however, on the new ones. There is no evidence that either of these times were chosen for a specific reason. As of Dec. 31, 2017, there are 12.5 billion Benjamins currently in circulation, according to the Federal Reserve Bank.
