Jaime Hernandez: This is the second year of issue for the Kennedy Half Dollar series. This year the Mint changed the composition of circulation strike Kennedy Half Dollars.
From 1965 to 1970 circulation strike Kennedy Halfs were produced from 40% silver and 60% copper nickel.
In 1965, the Mint also introduced Special Mint Sets which contained coins that were struck with a different finish than that of Uncirculated and Proof coins. The Special Mint Sets were only sold to collectors and were produced from 1965 to 1967.
