Coin orientation

Medallic orientation (or medal alignment, or variations of these) derives its name from medals tagged to a uniform. For a medal to display properly, when the obverse of the medal is right side up, a left or right turn must show the reverse also to be right side up. In other words, the tops of the obverse and reverse share the same position. In Britain this is sometimes called "British turnover". British coinage, most other Commonwealth coinage, Japanese yen coinage, and Euro coinage have medallic orientation.

Coin Alignment or Coin orientation is present when the top of the designs are aligned opposite of each other. The concept originated as a western style that was adopted by countries like Japan in the late 19th century.[1]
