The quantity of silver in a United States one-dollar coin is entirely dependent on the specific series and year of mintage. The term "silver dollar" can refer to several distinct types of coins, each with a different composition. The most commonly referenced silver dollars are the Morgan Dollar and the Peace Dollar. These coins, minted from 1878-1921 and 1921-1935 respectively, were composed of an alloy of 90% silver and 10% copper. The total weight of these coins is 26.73 grams, which equates to an actual silver weight of 0.7734 troy ounces per coin. Earlier silver dollars, such as the Seated Liberty Dollar (1840-1873), contained a similar amount of silver.
Following the cessation of silver coinage for circulation, the United States issued the Eisenhower Dollar from 1971 to 1978. The vast majority of these coins intended for circulation were made of a copper-nickel clad composition and contain no silver. However, special collector's editions were struck with a 40% silver clad composition. These 40% silver Eisenhower dollars contain approximately 0.3161 troy ounces of pure silver.
It is also critical to distinguish these historical circulating coins from modern bullion coins. The American Silver Eagle, first minted in 1986, has a face value of one dollar but is a bullion product not intended for circulation. Its value is based on its precious metal content, which is one full troy ounce of .999 fine silver. Therefore, the answer to how much silver is in a silver dollar varies from 0.7734 troy ounces for classic circulating coins to one full troy ounce for modern bullion pieces, with some collector issues containing different amounts.
