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)
