Coins - 1970 Mint
Three mints, Denver, Philadelphia and San Francisco, produced circulating coins in 1970 and contributed
uncirculated coins as examples of each coin they made to the 1970 Mint Set. In addition, the mint set included
a Kennedy half dollar which was not produced for circulation that year.
The mint set included one 40% silver half dollar, two each of the quarter, dime and nickel, and three
pennies. The 1970 Kennedy half dollar was the last year of the 40% silver coins until the special
bicentennial three-coin set.
Similar to the previous couple of years, the US Mint packaged the 1970 mint set in a plain white
envelope with the address of the United States Assay Office in San Francisco (the mint) in the return address area.
In the lower left corner "1970 — U. C." identifies the set. (U. C. = Uncirculated Coins)
1970 Mint Set Package
Two pieces of cardstock that have yellowed with age sandwich the two pliofilm sleeves containing
the coins inside the outer white envelope.
1970 Mint Set Uncirculated Coins
The red-edged pliofilm contains the five coins minted in Denver, including the Kennedy half dollar that did
not circulate in 1970, and a token printed with red ink. The four coins minted in Philadelphia and the
San Francisco one cent coin are in the blue edged pliofilm with a blue printed token.
Since the pliofilm does not hold the coins rigidly, they rotate into various positions in relation
to one another.
The coins' reverse images can be readily seen through the clear pliofilm. The tokens identifying
the mints show the same printing on the obverse and reverse views.
The red printed token in the 1970 mint set identifies that sleeve as being "Coins of
the Denver Mint."
Likewise, the blue printed token shows "Coins of the Philadelphia Mint & San Francisco Assay Office."
The San Francisco facility primarily minted proof coins, however they did produce Lincoln cents for
circulation and for the uncirculated mint sets.
