Based on the information provided, the standard total weight of a silver dollar is 26.73 grams. This specification was consistent for all Morgan dollars minted for circulation between 1878 and 1921.
The weight is a direct result of the coin's metallic composition, which consists of 90% silver and 10% copper. This alloy was standard for United States silver coinage of the era. The actual silver weight (ASW) contained within each coin is approximately 0.7734 troy ounces.
It is important for collectors to note that the weight of an individual coin can vary slightly from the official 26.73-gram standard. Coins that have been heavily circulated often experience minor weight loss due to wear and tear over time. Consequently, when weighing Morgan dollars, as some collectors do, slight deviations from the mint specification are not uncommon, especially for coins in lower grades.
