Well, that's what I was trying to figure out. I posted this on GMIC a few years ago. Really never got to the bottom of this. The Normandy Medal has stamped numbers in the side. One member posted a large index of Commonwealth medals. http://honours.homestead.com/comindex.html
I haven't heard or seen too many other medals like this. I was hoping to see what others here might have seen..
So here is the original post on GMIC. I would love to see others examples.
