1970 United States Mint Set in Original Government Packaging. The 1970-PDS Mint Set includes the last of the 40% Silver Clad Half Dollars, none of which were released into regular circulation. As a result, many 1970 Mint Sets have been broken up just so collectors can have an example of the Half Dollar. 1970 Mint Sets are found with either Large Date or Small Date Cents. The Small Date Set is approximately fifteen to twenty times as rare as the Large Date version. A scarce variety that is popular is the Large Date 1970-S Cent. This variety shows clear doubling of the mintmark. Some sets may contain one of the few different scarce 1970-D Doubled Die Reverse Dimes that show doubling of "UNITED STATES OF AMERICA". A rare variety of the 1970-D Quarter shows doubling of the "UNITED STATES OF AMERICA" and "QUARTER DOLLAR" on the reverse. Contents of the 1970 Mint Set included the cent, dime, and quarter from the Philadelphia Mint; cent, nickel, dime, quarter, and half dollar from the Denver Mint; and cent and nickel from the San Francisco Mint. The 1970-D Kennedy Half Dollar included in the set was struck in 40% silver and importantly was not issued for circulation. This created a low mintage key date for the recently released series and a draw for many collectors.
