Hello there! That's a great question about a classic American coin.
While the provided search results mention rolls of 1921 silver dollars for sale, they don't go into the specific metallic content of the coins. Based on my general knowledge, I can tell you exactly what you're looking for.
A 1921 U.S. silver dollar contains 0.7734 troy ounces of pure silver.
This figure applies to both types of silver dollars minted that year: the Dollar and the Peace Dollar. Both coins were produced with a composition of 90% silver and 10% copper. The total weight of the coin is 26.73 grams, and when you calculate the 90% silver content, it comes out to that 0.7734 troy ounce amount. This is often referred to as the coin's "Actual Silver Weight" or ASW.
