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:
“Since body and soul are radically different from one another and belong to different worlds, the destruction of the body cannot mean the destruction of the soul, any more than a musical composition can be destroyed when the instrument is destroyed.”
—Oscar Cullman. Immortality of the Soul or Resurrection of the Dead? The Witness of the New Testament, ch. 1, Epworth Press (1958)
“Vices enter into the composition of virtues as poisons into the composition of certain medicines. Prudence and common sense mix them together, and make excellent use of them against the misfortunes that attend human life.”
—François, Duc De La Rochefoucauld (1613–1680)
“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)
