Reverse: The reverse features a map of the world in the form of a Goode's Homolosine map. The words "US MAIL" are inscribed beneath it.  Around the edge is the phrase "BRINGING THE WORLD TO AMERICA'S DOORSTEP". 

Edge: The edge is smooth and contains the word "STERLING" along with a serial number at the top.
