The value of a US silver dollar in terms of its silver content is determined by its actual silver weight and the current market price of silver. US silver dollars minted before 1935, such as the common and Peace dollars, are composed of 90% silver and 10% copper.
The actual silver weight (ASW) in these Morgan and Peace dollars is approximately 0.7734 troy ounces. To calculate the intrinsic silver value, or melt value, you would multiply this weight by the current spot price of silver. For example, if the spot price of silver were $20 per troy ounce, the melt value would be 0.7734 multiplied by $20. Some earlier designs, such as Liberty Seated or Trade Dollars, have a slightly different silver weight, which would alter this calculation accordingly.
It is important to distinguish this silver melt value from the coin's numismatic or collectible value. The melt value represents the baseline worth of the coin based solely on its precious metal content. However, many silver dollars are worth significantly more to collectors due to factors like their rarity, condition, year of mintage, and mint mark. The silver value is therefore the minimum price a silver dollar is typically worth.
