Based on established numismatic specifications, a Silver Dollar in uncirculated condition has a standard total weight of 26.73 grams. This weight is derived from its composition, which is an alloy of 90% silver and 10% copper.
When converting this weight to ounces, it is crucial to distinguish between two different systems of measurement. In the troy ounce system, the international standard for weighing precious metals, a Morgan Dollar weighs approximately 0.859 troy ounces. In the more common avoirdupois ounce system, used for general purposes in the United States, the coin's weight is approximately 0.943 ounces.
For investors and collectors, the most significant figure is often the actual silver weight (ASW). Given its 90% silver content, a standard Morgan Dollar contains 0.7734 troy ounces of pure silver. It should be noted that these figures represent a coin in mint condition. As indicated by the practice of weighing individual coins, circulation causes wear that can slightly reduce a coin's mass over time.
