That's a great question! The provided search results didn't have the specific details, but I can certainly help you with that. The amount of silver in a U.S. silver dollar really depends on which coin you're talking about, as the composition has changed over the years.
For the classic silver dollars that most people think of, like the Dollar (minted from 1878-1921) and the Peace Dollar (minted from 1921-1935), the composition is 90% silver and 10% copper. These coins contain approximately 0.7734 troy ounces of pure silver. This is the standard for most U.S. silver coins minted before 1965.
Later, from 1971 to 1978, the U.S. Mint produced Eisenhower "Ike" dollars. Most of these that you'd find in circulation contain no silver at all; they are made of a copper-nickel blend. However, the mint also made special collector's editions that were 40% silver, containing about 0.3161 troy ounces of the precious metal.
Finally, there is the modern American Silver Eagle, which has been minted since 1986. While it has a face value of one dollar, it is a bullion coin not intended for circulation. These coins contain one full troy ounce of .999 fine silver. So, depending on the coin's era, the silver content can vary quite a bit
