Al SimeoneHi Mike,
I will take a shot at this. I would say that the pin you are showing is a repro. The front is very grainy. The back to me really tells the story. The real ones mostly all seem to have a nice little dimple circle dead center on the back (I hope my scan shows it) about the size of lets say a double pencil eraser. Also the collet Round ring on the back tends to be a little more rounded on the real ones. To me the obvious is the grainy photo on the front.
I hope this help you.
