The 1966 Special Mint Set, featuring the iconic Kennedy Half Dollar and Lincoln Cent, is a noteworthy offering for collectors, with a total mintage of approximately 2.2 million sets produced at the San Francisco Mint (S). This set is particularly significant as it marks the first year the Kennedy Half Dollar was issued in a mint set, following its introduction in 1964. The Lincoln Cent, with its distinctive design by Victor David Brenner, remains a staple in American numismatics, and the 1966 version is notable for its sharp details and brilliant finish. In terms of technical quality, coins from this set are often found with excellent luster and minimal contact marks, making them desirable for both type collectors and those seeking high-grade examples. The Kennedy Half Dollar, in particular, has seen increased interest due to its historical context, representing a period of national mourning and the subsequent celebration of a youthful president's legacy. As a semi-key date within the series, the 1966 Special Mint Set holds a unique place in the hearts of collectors, especially those focused on completing sets from the mid-20th century. The preservation of these coins, often found in original packaging, adds to their appeal, as collectors seek problem-free examples that exhibit the original mint brilliance.
