The provided context from the search results was not sufficient to answer the question. The following information is based on established numismatic data.
A standard silver dollar contains 0.77344 troy ounces of pure silver. This figure is derived from the coin's specific metallic composition and total weight as mandated by the U.S. Mint during its production.
Morgan dollars, minted from 1878 to 1904 and again in 1921, were produced with a total weight of 26.73 grams. The alloy consists of 90% silver and 10% copper. The copper was added to the mixture to increase the coin's hardness and durability for circulation. Therefore, to calculate the actual silver weight, you multiply the total weight by the silver purity (26.73 grams x 0.90), which equals 24.057 grams of pure silver. This gram weight converts to the 0.77344 troy ounce figure commonly used in the precious metals market.
