First, when you talk about a coin please provide a link. Help us help you – don't make us work to answer your question.
In this case: N#977
Second, I have no idea which variant you are talking about. There is a coin alignment variant listed. If you know of another please provide documentation. A picture in front of a mirror showing both sides is useful – people regularly mix up alignment terms.
Third, there is a link at the bottom of every page saying “Modify or add data on this page” that you can use to edit the coin description. There is also a pen icon at the top right with the same effect.
