60% copper and 40% silver.
All Kennedy halves are 30.6 mm in diameter. The weight depends on the year and metal composition 1964 (90% silver) = 12.5 gm 1965-69 (40% silver) = 11.5 gm 1971-present (copper-nickel) = 11.3 gm

Most silver dollars are made of metal alloys and are notelemental silver.

Kennedy half-dollars dated 1965-1970 contain 40% silver and 60% copper, with a total weigh of 11.5 grams. Using metal prices as of 17 February 2013, the copper in one 1965 half-dollar is worth 5.7 cents. The total melt value of the coin (silver + copper) is currently $4.47.
Please post a new question with a DATE. There aren't any solid silver JFK dollars for two reasons. First and most importantly, JFK's picture is on the HALF dollar, not the dollar coin. Look on the back for the denomination, like on all US coins. Second, no circulating coins are ever solid silver. It's way too soft and would wear out very quickly. It's always alloyed with another metal, usually copper. JFK halves contained silver for only 7 years: > 1964: 90% silver, worth about 0.36 times the current price of silver > 1965-70: 40% silver, about 0.16 times the current price of silver.
Penny has a silver metal around it and the dollar has only yellow
None. Redemption for silver metal was discontinued in 1968.
Silver and copper are not magnetic materials so no American 90% silver coin will stick to a magnet.
As opposed to fake silver, LOL? All 1971 and later circulation-strike half dollars are made of the same copper-nickel clad metal used in dimes and quarters. They have no extra value.
It is 90% silver and 10% copper.
The metal content of a 1980 silver dollar is 90% silver and 10% copper. That compisition is the same for all dimes, quarters and dollar coins up till 1964 when the compistion changed again to 90% copper and 10& nickel.
