Extremely improbable that you found a 1964 SMS half. I'm sure that you read in the PCGS write up that ALL of them were found in the estate of a former mint director and acquired by a major dealer 20+ years after they were minted. How would a coin like this get into circulation? The known examples were minted in Philly. Your coin was minted in Denver. I'm sorry for the skepticism, but you believe you have something extraordinary, and extraordinary claims require extraordinary proof. No "it looks like" or "it might be". It must be exact!
email out to them see if they would attribute it I'll let you know the outcome thank you I completely understand I'm skeptic but I also go by it is what it is it's identical except for the D I sent you an email out for an attribution will see what they say thank you for your honesty and your comment
I assume you meant that they melted the 1964-D Peace dollars. What reason would there be to melt 1964-D half dollar SMS coins? There is none. Your coin does not match the markers for the SMS coin. And as Sully said, they didn't make them in Denver anyway. The odds that you have the discovery coin is almost zero. (It's actually 0, but I'm not going to say it. Whoops, I just did.)
Nothing it is a point. like your knowledge on this subject you should do better research. And Get glasses
Clearly you didn’t understand what I said (just like you don’t understand basic facts). Send the coin in, when it comes back as no an SMS coin, I look forward to the thread where you complain about how they were wrong also.
They did not make any 1964 D SMS coins. That is NOT the "teardrop" marker seen on the 1964 SMS half dollar. This is the teardrop.
