1970-S Proof Set

1970 was the last year of the 40% Silver Clad Half Dollars, but none were released into circulation. To obtain a 1970 Half Dollar from any of the mints, collectors had to purchase either a 1970 Proof Set or a 1970 Mint Set. The appearance of two major Cent varieties (Large Date and Small Date) created additional interest in Proof Sets of this year. Today's price of 1970-S Proof Sets remains strong because it is still possible to find the more valuable 1970 Small Date Sets at the regular price.

Each set contained five coins: One example each of the Lincoln Cent, Jefferson Nickel, Roosevelt Dime, Washington Quarter, and Kennedy Half Dollar.

About the sets: 1970-S Proof Coins are found with Brilliant, Cameo, and Deep Cameo surfaces. Deep Cameo Proof coins are the most desirable of the three finishes.

Mintage: 2,632,810 sets

1970 was a great year for the Proof Set collector with the discovery of the rare "S"-less Dime variety and the 1970-S Cent Small Date variety. Three other rare varieties appeared including a 1970-S Cent with both a Doubled Die obverse and a Large Date over a Small Date. A 1970-S Large Date with a Doubled Die obverse and one with a Triple Die obverse. Both the Doubled Die obverse and Triple Die obverse show doubling on "IN GOD WE TRUST", the date, and "LIBERTY". The 1970-S Small Date variety and Large Date variety can be distinguished by looking at LIBERTY, Liberty on the Small Date variety will be weak and on the Large Date variety will be strong. Another method to identify the two varieties is to look at the date. On the Small Date variety the top of the 7 is level with the tops of the 9 and the 0. On the Large Date variety, the top of the 7 is below an imaginary line connecting the tops of the 9 and the 0. The mintage of each variety is unknown, but the Proof 1970-S Small Date is valued about 50 to 60 times the Proof 1970-S Large Date.

Approximately 2,200 Proof 1970-S Dimes were struck without a mintmark. Although Proof coins were being struck at the San Francisco Mint at the time, responsibility for making the Proof dies (and adding the mintmark) rested with the Philadelphia Mint. Apparently, one die was sent from Philadelphia without the mint-mark, and a small number of "S"-less Dimes were struck and released before the error was discovered. The Mint confirmed that only a single die pair had been used to strike the "S"-less Dimes, and the Mint provided the estimated mintage figure. Because the "S"-less Proof sets are quite valuable, be sure to examine the plastic case for signs of tampering and substitution. Do not purchase an individual "S"-less Dime or complete Proof Set, unless it has been authenticated by an expert.

Original packaging: The individual coins of the 1970-S Proof Set were placed into holes in a black plastic insert, then sealed in a two-piece, clear plastic case. The case was then inserted into a protective outer cover consisting of blue cardboard, imprinted with the words: "United States Proof Set • 1970."

San Francisco - S
Established in 1853 to strike coins from California’s newly-discovered vast reserves of gold, the San Francisco branch of the United States Mint is famous for the quality, lustrous Morgan Silver Dollars produced at "The Granite Lady" from 1878 to 1921. After moving to a new building in 1937, coin production at the San Francisco mint shut down in 1955. A shortage caused regular coin production to resume in 1965. While the mintage of circulating coins ceased in 1981, proof coins and commemoratives are still struck at the San Francisco Mint today.
