Based on established numismatic data, a silver dollar has a standard weight of 26.73 grams. This specification was determined by the United States Mint and adhered to throughout the coin's production from 1878 to 1904, and again in 1921.
The coin's composition is a crucial factor in its total weight. Morgan dollars were minted from an alloy of 90% silver and 10% copper. This means that the actual silver weight within a standard, uncirculated coin is approximately 0.7734 troy ounces, or 24.057 grams. The copper was added to the alloy to increase the coin's hardness and durability for use in circulation. It is important to note that coins that have been heavily circulated may weigh slightly less than the mint specification due to wear from handling over time.
