the u.s. mint has also released special proof sets, such as in 1976, when a proof set of three 40% silver-clad coins: the quarter, half-dollar and dollar coins depicting special reverses to commemorate the u.s. bicentennial was issued. from 1971 to 1974, proof silver-clad eisenhower dollars were issued in a plastic case contained in a brown wood-grain finish slipcase box, and are referred to as "brown ikes". proof susan b. anthony dollars were struck in 1999. although these proof dollars were sold separately and not included in the proof sets for that year, some third parties used the cases from other years to create 1999 proof sets that include the dollar, prompting the u.s. mint to advise the public that these sets were not government-issued sets. a proof "coin & chronicles" set was issued for 2009, which included one each of the 4 different lincoln cent designs and a commemorative lincoln silver dollar, presented in special packaging. other sets, called "prestige proof" sets, also contain selected commemorative coins. these sets were sold from 1983 to 1997 (except 1985) at an additional premium. as legacy proof sets, the practice was resumed from 2005 to 2008.
