Silver half dollars have about 0.362 Troy oz. of silver in them, so 3 of them would be 1.086 Troy oz.
The answer will depend on which country's dollar!
3 well equal a little more than a ounce of silver.
A standard U.S. silver half dollar, minted before 1965, contains 0.3617 ounces of silver. To make 1 ounce of silver, you would need approximately 2.76 silver halves. Since you can't have a fraction of a coin, you would need to use 3 silver half dollars to exceed one ounce of silver.
Each Kennedy half that was minted in '64 or earlier had .36 troy oz of silver meaning a little less than three would equal an ounce of silver which is running for 29.30 an ounce last i checked. <><><><> Half dollars made 1965-1970 contained only 40% silver, instead of the 90% of earlier coins, so it would take more coins. Half dollars made after 1970 contain no silver.
Half dollars dated 1965-69 were struck in silver-clad metal, 80% silver on the outside and 20% silver in the core. The rest was copper, for an overall composition of 40% silver.
