The amount of silver in a United States silver dollar varies depending on the specific series and the year it was minted. The provided search result context was not useful for extracting specific data, as it consisted primarily of website navigation elements rather than substantive content. Answering the question requires a broader numismatic knowledge base.
Historically, the most common silver dollars that circulated as currency are the Morgan Dollar (1878-1904, 1921) and the Peace Dollar (1921-1928, 1934-1935). These coins were minted from a composition of 90% silver and 10% copper. By weight, each of these coins contains 0.77344 troy ounces of pure silver. Earlier silver dollars, such as the Seated Liberty Dollar (1840-1873) and its predecessors, also contained a similar amount of silver, approximately 0.7734 troy ounces.
It is important to distinguish these historical coins from later issues. For instance, the Eisenhower Dollar (1971-1978) was primarily a copper-nickel clad coin intended for circulation and contains no silver. However, special collector's editions were struck in a 40% silver composition, containing 0.3161 troy ounces of the precious metal.
Furthermore, the modern American Silver Eagle, first minted in 1986, is a bullion coin with a face value of one dollar. Unlike the historical circulating currency, this coin is specifically designed for investment and contains exactly one troy ounce of .999 fine silver. Therefore, specifying the type of silver dollar is crucial to accurately determine its silver content.
