The American greenback

The good old greenback !! The American dollar is certainly the most commonly used and well known currency in the world. From the remotest African villages to the borders of the Mekong, no one will refuse to be paid in dollars. If you have a few of them in your pocket, you are surely holding a piece of the world. Tell that to the Chinese!

However, as far as originality goes, the American currency is somewhat lacking. From the 1-dollar bill to 100, the USD is printed in the same format: on the front, there are the great presidents from American history (Washington, Lincoln, Franklin, etc.) and on the back, there are great monuments (the White House, the Capitol Building, etc.).

And only since the 2009 series have the presidents' busts been freed from their oval confines and a touch of color (other than green) was added to some banknotes (violet to the $5 bill and yellow on the $10 bill).

As for coins, the story goes a little differently. Unlike the banknotes, many commemorative coins or series have been regularly released into circulation. And all the face values are used: from the cent to the dollar, including the dime (10 cents) and the quarter (25 cents). You can find:

• the President Series on $1 coins which since 2007 have commemorated different presidents of the United States who have been deceased at least 2 years, at a rate of 4 coins per year in the order of their presidency
• the Native American series: since 2009 with Sacagawea on the front
• the "America the Beautiful" quarter series: since 2010, featuring national parks and other sites.

On banknotes as well as coins, you can find 2 mottoes that are also well known all over the world:

• E pluribus unum (Out of many, one): present on all coins since 1873
• In God We Trust: the motto of the United States, present on all coins since 1908 (although it wasn't the national motto at the time) and on all banknotes.
