Composition
The Eisenhower dollar was struck with a copper-nickel composition for circulation and was the first United States dollar coin to not be struck in a precious metal. While the circulated copper-nickel coins contained no silver, they were often incorrectly referred to as "silver dollars" by the general public. The only Eisenhower dollars to actually contain silver came from special collectors' issues struck at the San Francisco Mint in a silver-copper composition, the same as the 1965-70 Kennedy half dollar.
Copper-nickel issues:
- Weight: 22.68 grams
- Composition: Outer Layers of 75% copper, 25% nickel with a center layer of 100% copper
Silver-copper issues (silver clad):
- Weight: 24.59 grams
- Composition: Outer layers of 80% silver with a center of 20.9% silver. Aggregate 60% copper, 40% silver
- Silver content: 0.3162 troy ounce (9.836 grams)

Famous quotes containing the word composition:
“The naive notion that a mother naturally acquires the complex skills of childrearing simply because she has given birth now seems as absurd to me as enrolling in a nine-month class in composition and imagining that at the end of the course you are now prepared to begin writing War and Peace.”
—Mary Kay Blakely (20th century)
“Give a scientist a problem and he will probably provide a solution; historians and sociologists, by contrast, can offer only opinions. Ask a dozen chemists the composition of an organic compound such as methane, and within a short time all twelve will have come up with the same solution of CH4. Ask, however, a dozen economists or sociologists to provide policies to reduce unemployment or the level of crime and twelve widely differing opinions are likely to be offered.”
—Derek Gjertsen, British scientist, author. Science and Philosophy: Past and Present, ch. 3, Penguin (1989)
“Viewed freely, the English language is the accretion and growth of every dialect, race, and range of time, and is both the free and compacted composition of all.”
—Walt Whitman (1819–1892)
