Quote:
The 1964 SMS Kennedy half dollar is one of the most elusive modern United States coins and is by far the rarest non-error, non-die variety Kennedy half. Mystique shrouds the existence of 1964 SMS Kennedy half dollars, of which there are just 12 known examples. There is relatively little verified information explaining their origin or provenance, and the mystery coins are scarcely offered for sale.

How To Tell A 1964 SMS Kennedy half dollar from a Business Strike Or Proof
The 1964 SMS Kennedy half dollar that just sold for nearly $50,000 has a satin-textured surface, which is the general appearance of all 1964 SMS halves. Salmon-orange rim toning kisses the upper obverse and lower reverse surfaces of the coin with ambient white-gray coloration across the fields and devices. Surface marks on the lower obverse that mimic dark fingerprints are described by Heritage as "carbon-gray flecks."

Overall, the coin boasts strong details and a sharp, square wire rim - features seen on other 1964 SMS Kennedy half dollars. Die polishing marks and an absence of contact marks further indicate these 1964 Kennedy half dollars were specially struck and not simply high-end business-strike specimens. These coins do not display the mirror-like reflective surfaces that are seen on proof coins, yet they have a stronger strike than seen on either the 1964 proof coinage or SMS coinage from 1965 through 1967.

Another important die marker on the 1964 SMS Kennedy half dollar is known as a "dangling 4". This diagnostic is a tiny, teardrop shaped piece of metal that descends below the 4 digit in the coin's 1964 date.
