A standard silver dollar has a total weight of 26.73 grams. The coin's composition, as established by the U.S. Mint, is 90% silver and 10% copper.
This specific alloy means that the actual silver weight (ASW) contained within a Morgan dollar is .7734 troy ounces. The addition of copper was a standard practice to increase the durability of the coins for circulation, helping them withstand daily wear and tear.
