The provided search result context does not contain the specific weight of a silver dollar. However, drawing upon established numismatic data, the weight of a U.S. silver dollar varies depending on the specific coin being referenced.
The most common historical U.S. silver dollars, such as the Dollar (minted from 1878-1904 and again in 1921) and the Peace Dollar (minted from 1921-1935), have the same specifications. These coins, composed of 90% silver and 10% copper, have a total weight of 26.73 grams. In terms of silver content, this equates to approximately 0.7734 troy ounces of pure silver per coin. The troy ounce is the standard unit of measurement for precious metals.
It is crucial to distinguish these historical coins from the modern American Silver Eagle, which is a bullion coin produced by the U.S. Mint since 1986. While it has a face value of one dollar, its primary value is based on its silver content. The American Silver Eagle contains exactly one troy ounce of .999 fine silver. Therefore, the weight of a "silver dollar" in ounces is typically either 0.7734 troy ounces for historical issues or one troy ounce for modern bullion coins.
