The 1970-D Kennedy Half dollar is among the most popular mint state coins in the Kennedy Half series. They were the last to be struck in the 40% silver alloy used since 1965 and were only sold in mint sets. Even though they were only released in sets, they were generally of poor quality and are extremely rare above MS66.
