The amount of silver in 50 dimes depends entirely on the year they were minted. United States dimes manufactured for circulation in 1964 or earlier are composed of 90% silver. Dimes produced from 1965 to the present day do not contain any silver.
Assuming the 50 dimes in question are from 1964 or earlier, such as the Roosevelt (1946-1964) or (1916-1945) series, each coin contains 0.0723 troy ounces of pure silver.
To determine the total silver content for 50 of these dimes, you would multiply the silver weight per coin by the quantity. This calculation results in a total of 3.615 troy ounces of silver for 50 pre-1965 dimes. If the 50 dimes were minted in 1965 or later, their silver content would be zero.
