1970 Proof Set

1970 Proof Set1970 US Mint Proof Set

The 1970 Proof Set showed a marked decline in mintage from the prior two years sets. The line up was the same five coins, one for each denomination minted at the San Francisco Mint and carrying the “S” mint mark. Notably, this year was the last time the Kennedy Half Dollar struck in 40% silver for circulation. The 1970-S Kennedy Half was the last 40% silver coin produced for inclusion in an annual proof set until the composition was revived for a special 1976 Silver Proof Set.

The face value of the coins was 91 cents and the sets were sold by the US Mint for $5.00 each. The original packaging consisted of the coins sealed in a plastic lens with a black plastic holder for the coins. This was placed into a blue cardboard box.

The 1970 Proof Set has a few variations of interest. Some of the 1970-S Proof Lincoln Cents have a small date, similar to the small date variety for the circulating version of the coin. The small date sets are worth considerably more than large date sets. A small number of 1970 “No S” Proof Roosevelt Dimes were produced. It is estimated that approximately 2,200 dimes were struck without a mint mark.
