1965, 1966 & 1967 Special Mint Set Trio

Product Description

Since 1951, the U.S. Mint has issued separate proof and mint sets annually, with the exception of the 1965-1967 span. This transitional period fell between the last Philadelphia proof set of 1964 and the first San Francisco proof set of 1968.

During these years, the U.S. Mint replaced proof sets with a higher quality form of mint sets. Like previous proof sets, each "Special Mint Set" contained all five denominations for the date: cent, nickel, dime, quarter and 40% silver Kennedy half dollar. These hybrid sets had mintages far lower than proof sets of the time. This trio includes all three special mint sets, including the costliest 1967 — whose mintage of just 1.9 million makes it a key scarcity.
