A silver dollar contains 0.7734 troy ounces of pure silver. This figure represents the coin's actual silver weight.
The total weight of a Morgan dollar is 26.73 grams, which is equivalent to approximately 0.859 troy ounces. However, the coin's composition, as established for its minting period of 1878-1904 and 1921, is 90% silver and 10% copper. When you calculate 90% of the total mass, you arrive at the actual silver content of 0.7734 troy ounces. The remaining weight is comprised of the copper alloy, which was added to increase the coin's durability for circulation.
