@MisterGarrett: I will not give you the history of the SMS essay of the Mint, also same of the declaration from EVA regarding those essays in front of the congress because I already put here on the forum. You look at some YouTube video which no one are 100% accurate. I give you here the photos of the markers parts of the Observe. Do not forgot that also the Reverse has some which are characteristic just for this strike of approx.. 50 sets which no one made the way in the wild.
Those sets was capsulated in special plastic kind and from 50sets, 49 are already accounting. The last one not declared yet is already supposed where it is.
Here the photos of authentic SMS 50 cent 1964. You can compare with your coin to see the big differences.
