Finest known with highest eye appealAs the only silver issue of the bicentennial half dollar, this 1976-S Silver Kennedy Half Dollar is an enormous rarity! And it is graded in perfect Proof 70 Ultra Cameo condition, making it the finest known! To add to the rarity, this is currently the only perfect PF70 UCAM example housed in Rick Tomaska’s Signature Series holder, denoting that it has the highest eye appeal for the date and grade. Although mint records show that a little over 7 million examples were struck, many coins were melted down in 1982.
