The U.S. Mint never made silver certificates because the Mint only strikes coins. Paper money is made by the Bureau of Engraving and Printing. The last silver certificates were printed in the early 1960s, but all were in the 1957 series.
1964 was the last year the mint minted Half Dollars in 90% silver. Then from 1965 to 1970 they were struck in 40% silver. Currently Half dollars contain no silver. They are made of a copper-nickel clad composition. Starting in 1992 the mint started making 90% silver proofs. In 1964 dimes, quarters and dollars were also stopped being made in 90% silver.
The last $20 silver certificates were issued in the 1891 series. While all denominations from $1 to $1000 were printed at different times during the 19th century, only $1, $5, and $10 silver certificates were printed in the 20th century. Production of $5 and $10 silver certificates ended with the 1953 series, and $1 silver certificates ended with the 1957 series. At that time series dates were rarely changed, so silver certificates were actually printed into the 1960s with those same years on them but different letters.

1867
Inflation caused the silver content of coins to be worth more than their face value so the US mint stopped making silver coins for circulation.
