The number of silver dollars it takes to make an ounce depends on the weight and purity of the silver dollar. In general, a standard silver dollar weighs 26.73 grams, or 0.859 troy ounces, and is made of 90% silver and 10% copper. This means that each silver dollar contains approximately 0.77344 troy ounces of pure silver.

To determine how many silver dollars it takes to make an ounce of silver, we need to divide 1 by the weight of a single silver dollar in ounces. Using the weight of a standard silver dollar, we can calculate that it takes approximately 1.163 silver dollars to make an ounce of silver.
However, it’s important to note that not all silver dollars are created equal. There have been many different types of silver dollars minted throughout history, each with different weights and purities.
For example, the Morgan silver dollar, which was minted from 1878 to 1904 and again in 1921, weighs 26.73 grams and is made of 90% silver and 10% copper, just like the standard silver dollar. However, the Peace silver dollar, which was minted from 1921 to 1935, weighs 26.73 grams and is made of 90% silver and 10% copper, but also contains a small amount of manganese to improve its resistance to wear and corrosion.
Other types of silver dollars, such as the Trade dollar and the Seated Liberty dollar, have different weights and purities. The Trade dollar, which was minted from 1873 to 1885, weighs 27.22 grams and is made of 90% silver and 10% copper, while the Seated Liberty dollar, which was minted from 1840 to 1873, weighs 26.73 grams and is made of 90% silver and 10% copper.
In addition to these standard silver dollars, there are also commemorative silver dollars that have been minted for special occasions, such as the 1986 Statue of Liberty commemorative silver dollar. These commemorative coins are often made of higher purity silver, typically 99.9% pure, and may have different weights and dimensions than standard silver dollars.
In general, the weight and purity of a silver dollar will determine how many coins it takes to make an ounce of silver. A standard silver dollar, which contains 0.77344 troy ounces of pure silver, would take approximately 1.163 coins to make an ounce of silver. However, other types of silver dollars may require a different number of coins to make an ounce, depending on their weight and purity.
It’s also worth noting that the price of silver can fluctuate significantly based on supply and demand, economic conditions, and other factors. As of March 2023, the price of silver is approximately $24 per ounce, meaning that it would cost approximately $24 to purchase an ounce of pure silver. The price of a silver dollar, on the other hand, can vary based on factors such as its rarity, condition, and historical significance.
Overall, while the number of silver dollars it takes to make an ounce of silver can vary based on the weight and purity of the coins, it’s important to keep in mind that the value of silver dollars and other precious metals can be influenced by a wide range of factors. Investors and collectors should carefully consider these factors when making decisions about buying or selling silver coins.
