2) Having the Same Dollar Bill Color

You will agree with me that the U.S. currency is pretty dull for a country that’s the largest economy in the world based on GDP. While other countries boast of more fanciful and colorful bills with historical figures, the U.S. remains adamant about retaining its famous green color. All denominations are the same size, the same design, and are of the same color. A foreigner might find it hard to distinguish between the notes, as they are almost similar and have the same shade of green, save for different historical figures on the bills. So if you are planning to visit the US soon, be conscious of this and always verify the amount printed on the bill.
