I added a picture of normal initials from a quarter with the same year/ mint/ design (ozark riverways) for comparison.
Please try to understand that super-duper enlargements are meaningless when it comes to searching for doubled dies. If you have to use extreme magnification to see something, it is too minor to be considered important. That is not to say that some people won't collect them. Why? I don't know! But, in this case, I think you just have something that was "picked up along the way" during it's period of circulation. Chris
