I think referring to them as medals isn't the best idea. The Legion is far from the only organization that hands out unofficial medals to its members. The Legion is very specific about when they can be worn (on the right side, only on Legion uniform), and they have made them distinctly different from traditional medals, they are noticeably smaller, and for the most part, they all have the Legion badge on them.
Unfortunately, you will occasionally see people abuse them and wear them when not in a Legion uniform or mount them with medals from multiple organizations. However, at least you don't see people wearing them on the left side with recognized medals in a way that many first responders are guilty of, I've even seen some of those people wearing them on military uniforms as well. They are generally a high enough rank that no body charges them.
