An pre-1965 U.S. dime weighs 2.5 grams total. The silver content of pre-1965 dimes, quarters, halves, and silver dollars is 90% silver by weight, so there is 2.25 grams of silver in an unworn, uncirculated pre-1965 U.S. dime.
Up to and including 1964 they were 90% silver. After 1965 they contained no silver except for special coins the mint produced for collectors.
Up till 1964, U.S. quarters (as well as dimes and half dollars) were struck in an alloy of 90% silver and 10% copper.In 1964 the price of silver increased to the point where quarters contained much more than 25¢ worth of silver. Starting in 1965, quarters and dimes were made of a 3-layer "sandwich" consisting of a pure copper core with outer cladding of 25% nickel and 75% copper, for a total of about 92% copper, 8% nickel.Note about half-dollars and dollars : From 1965 to 1969 half-dollars were made of 40% silver. They weren't made for circulation in 1970. In 1971 half dollars were converted to the same sandwich metal as dimes and quarters. Dollars were also made from copper-nickel until 2000, when the current gold-colored brass metal was used.
