Kennedy half dollar
Notable are the 1970, 1973, and 1996 mint sets. These contained the 1970-D Kennedy half dollar, the 1973-P and 1973-D Eisenhower dollars, and the 1996-W Roosevelt dime, none of which were minted for general circulation and could be obtained only from the U.S. mint sets. More recent sets contain non-circulating half-dollar and dollar denominations. From the 2005 mint set coins through the 2010 mint set coins were prepared using special dies that produce a "satin finish" distinct from business strike coins. The US Mint reverted to coins that are typically minted for general circulation in 2011. Mint sets currently are sealed in a plastic blister-pack, unlike the flexible plastic packs of earlier sets. They are usually sold in sets of two - one for each branch of production.
