Hello - I could use an experts' advise please.
It seems very unlikely that I have a 1964 SMS proof set, but I have not been able to find anything in my research (yet) that leads me to believe this is not the real thing. I've posted some pictures that I would appreciate you looking at and would be more than happy to zoom in and send additional pictures of any of the coins details. I hope an expert can tell me what I really have here and what to look for.
Thank you in advance for your help.
