Why is the Flip Side 'Flipped'?
Why is the picture on the back of a coin upside down compared to the front?
All U.S. coinage is produced in this way, commonly called a "coin turn." Mint research has not determined the exact reason for this tradition. It is not required by law.
The alternative is called a "medal turn." In that case, the back and front have the same orientation because medals are traditionally made to hang from a ribbon at the top.
