Well, while the provided search results are fascinating examples of coin dealer websites, they're surprisingly shy about giving up the actual goods on the coin's composition. They're about as helpful for this question as a screen door on a submarine.
Fear not, for the answer is a classic. A 1921 dollar, just like all of its earlier brethren, contains precisely 0.7734 troy ounces of pure silver.
These hefty pieces of American history were minted from an alloy of 90% silver and 10% copper, giving them a total weight of 26.73 grams. The U.S. Mint added that dash of copper to make the coins tough enough to survive the rough and tumble world of commerce back in the day. So, when you do the math and separate the precious from the practical, you're left with that key 0.7734 troy ounces of the good stuff.
