The provided search results do not contain the specific technical data required to answer the question. However, based on established numismatic information, the silver content of a silver dollar is standardized across all years of issue, including 1886.
A Morgan silver dollar has a total weight of 26.73 grams and is composed of 90% silver and 10% copper. This composition was mandated by the Coinage Act that authorized its production.
To determine the actual amount of pure silver, one calculates 90% of the coin's total weight. This results in an actual silver weight (ASW) of approximately 24.057 grams. In terms of the standard unit for precious metals, this is equivalent to about 0.7734 troy ounces of silver. This figure represents the amount of silver in an uncirculated coin; a coin that has experienced wear through circulation will have a slightly lower total weight and, consequently, a marginally reduced silver content.
