Belgium, 2 Euro UNC 2006, Atomium, Rotation 30 degrees.
Strike due to a corner unscrewed and having generated a coin whose axis is no longer the theoretical axis. The amount of off-centering is measured in hours or degrees. Example: a coin is called "offset at 1 o'clock" when the reverse is at 1 o'clock while the obverse is at 2 o'clock. In this case, we can also say that the offset is 60 degrees.. (Google Translate).
