I believe it to be a lapel button, I certainly could be wrong wouldn't be the first time. That backing looks as if it is to go into the boutonnière hole on the lapel. What an odd piece and who it depicts makes it even more so as to why someone would wear it. To each his own I guess. Great find and job finding it.
I have hundreds of buffalo nickels (without date) that someone said would make nice cuff links, just wish I could I could find that person to sell them.
