Clad coins are regular coins, all US dimes, quarters, half's and dollars made since 1965 to date are "clad". Each coin has a center core of pure copper and a layer of copper-nickel or silver on both sides of the coins. The only coins made for circulation after 1965 that had any silver were the 1965 to 1969 Kennedy half dollars but they are 40% "silver clad" coins.
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.
Yes. The composition was changed to 40% silver in 1965 and to copper-nickel clad in 1971.

Clad Quarters have copper, and silver color on the edge. 1965- Current are copper clad. Only on half dollars did they make 40% silver coins from 1965-1970. No circulating US coins were ever made of solid silver. They had 10% copper in them to make the metal hard enough to resist wear. 90% Silver Quarters are silver colored on the edge. Some may have toning. 90% Silver Dimes, Quarters, Half Dollars, and Dollars were minted until 1964. Some special current coins are silver, but are only in silver Proof Sets, and cost more than a regular Clad Set. Some Eisenhower Dollars from San Francisco have 40% silver content.
Modern copper clad Kennedy half dollars dated 1971 or later weigh 11.34 grams, though the weight may be slightly less if the coin is worn.
The actual term is "clad" rather than "layered". Clad coinage of dimes and quarters started in 1965 when silver became too expensive to use in coins. Half dollars were struck in clad silver from 1965 to 1969, but by 1971 they too were made out of copper-nickel like the smaller coins.
Kennedy half dollars are still minted for general circulation in Copper-Nickel Clad Copper for circulation while some Proofs (San Francisco Mint {S}) are made in Silver. Check with your favorite federal bank for one or in rolls.
US clad coinage began in 1965. Since then all dimes and quarters have been made of a pure copper core with outer layers of 25% nickel and 75% copper. Halves were made of clad silver (80% copper/20% silver core, and the opposite on the outside) from 1965 to 1970. In 1971 the half dollar was changed to the same composition as dimes and quarters. Eisenhower and SBA dollars are also made of the same copper-nickel clad metal. Sacajawea and Presidential dollars are made of copper clad with layers of manganese brass. Regardless of popular misunderstandings, nickels have never been made of clad metal, and since 1982 cents have been made of plated (but not clad) zinc.
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.
