The Kennedy Half Dollar series saw collectible offerings expand during the years 1990 to 1999. After many years of a standard proof version and two issues struck for circulation, a third annual release was added to the mix. Additionally, a one-time special issue was offered as part of a commemorative coin set.
Starting in 1992, the US Mint began issuing a Silver Proof Set. These sets included the half dollar, quarter, and dime struck in a composition of 90% silver and 10% copper. The offering was met with success and continued to be issued for each subsequent year, creating a new regular issue for each coin series. Some of the 90% Silver Proof Kennedy Half Dollars issued during the mid-1990’s had very low mintages which result in high premiums.
In 1998, the US Mint issued commemorative coins to honor Robert F. Kennedy. A special set was issued which included the commemorative coin paired with the half dollar featuring John F. Kennedy. The half dollar was produced using a special matte proof finish. Because of the small number of sets issued, this has become a valuable collector coin.
