A 1900 dollar contains 0.7734 troy ounces of silver. This figure represents the actual silver weight (ASW) of the coin.
The standard composition for all Morgan dollars, including the 1900 issue, is 90% silver and 10% copper. The total weight of the coin is 26.73 grams. The specific amount of pure silver is calculated based on this total weight and its 90% purity, resulting in the widely recognized 0.7734 troy ounce figure. These specifications are consistent across the entire Morgan dollar series, minted from 1878 to 1921.
