It is a medal from a lodge convention or Reunion. I am not sure what the name of the organization is though. I have some from the Elks, if I can figure out where I put them, I will post a few of them. Usually, each year their convention is held at a lode in different states. When a member attended a convention, they were given one of these or possibly had to buy it. I am not sure which. On second thought, I believe maybe just one member delegated from each lodge would attend the convention. I would say that the empty rectangular spaces at the top of the medal most likely held the persons name in one space , and what lodge he or she represented in the other. I am not a lodge member of any kind, maybe someone on here that is will clarify.
I also figure, I will not be able to figure out where I have the ones I have, so I went back and got these off of eBay for you to see.
And I thank you Sir ! I was pretty sure it was a ladies society, never even gave the bottom letters a thought as for recognizing who they represented ! Thanks for clearing that part up for me.
