Keep reading this article to learn the importance of knowing the precise weight of silver coins, how it can affect their value, and how it can help you identify counterfeits.

Why is a coin's weight relevant?

While the most common type of counterfeiting among Morgan dollars involves adding an "S" mintmark to the 1893-P Morgan Dollar (since Philadelphia mint coins do not bear any mint mark), understanding how weight affects a coin's value is crucial in coin collection.

In the precious metals market, the Troy oz system is the standard unit for measuring gold, silver, platinum, and palladium.

The troy ounce used for precious metal coins, including gold coins, equals precisely 31.1034768 grams.

Understanding a coin's weight is essential (though not the only method) for distinguishing between authentic pieces and counterfeits. Due to the varying masses of different metals, the weight of a silver coin serves as a reliable indicator of the authenticity of the silver content.

Furthermore, because silver is priced according to its weight, the value of a silver coin is calculated by multiplying its weight by the silver spot price plus the dealer's premium.

Therefore, knowing its precise weight is paramount to understanding how much a Morgan Silver Dollar is worth.

Historical Context

The name of the new silver dollar comes from its designer, George T. Morgan, a United States Mint Assistant Engraver at the time.

The existence of the Morgan Silver Dollar can be attributed, at least in part, to the provisions of the Sherman Silver Purchase Act.

Enacted on July 14, 1890, the Sherman Silver Purchase Act mandated that the United States Treasury increase its purchases of silver, aiming to boost inflation, which was seen as beneficial for farmers at the time.

This requirement for increased silver purchases directly motivated the production of silver coins, including the Morgan Silver Dollar.

Even though Morgan silver dollars production went on hiatus, the coin's standard weight remained the same. Although there are slight variations depending on different mint facilities, an authentic Morgan silver dollar should weigh 26.73 grams.

The US Mint has recently released a new, collectible version of Modern Morgan Silver Dollars. These coins come in an original display box with a Certificate of Authenticity. They celebrate the history of American coinage and are a real testament to the US Mint’s continued work to provide the country with the epitome of craftsmanship.

Factors Affecting the Value of Morgan Silver Dollars

Silver Content

The modern Morgan Dollars and the Peace Dollar, released by the US Mint in 2021 and then again in 2023, are 99.9% silver bullion coins, primarily for commemorative and collectible purposes.

Weight variations across different United States mints

There are slight variations in the Morgan Dollar's weight across the different US Mint branches.

  • San Francisco coins tended to be underweight compared to the standard, with an average weight of 26.65 grams.
  • Carson City Morgans typically vary around the weight of 26.75 grams.
  • New Orleans Morgans generally average around 26.7 grams.
  • Denver Morgans averaged between 26.50 and 26.60 grams in the early 1920s.

Notable Mints and Dates

The value of this one coin is based on its pure silver content and premium, as it is a collectible item. Sometimes, specific dates will increase their premium because of their scarcity or historical significance.

Coins with certain years or mint marks are considered key-date coins. A key date is often defined as a coin that is scarcer than a common coin and harder to obtain in a series.

Some factors that influence whether a coin is a key date include demand, the number of coins struck, the population of surviving examples, and the rarity of mint-state examples.

See below the most outstanding key dates for the Morgan silver dollar series:

    • The lowest mintage of the business strike Morgan silver dollar back in the day was in 1893 in San Francisco. Only 100,000 coins were struck, making this a key date in the Morgan series and very rare in Mint state. Most of them can only be found in private coin collections;
    • The second lowest mintage and also a very popular variety is the 1894 Philadelphia Morgan dollar, which had a strike of 110,000 that year;
    • 1895-O is very rare in Mint State conditions. As of March 2024, PCGS reported less than 200 hundred uncirculated specimens;

    • The Morgan dollars from Denver are also a key date because they were exclusively produced in 1921. So, if you ever come across a Denver coin, it must have the date 1921;

    • The coins from Carson City Mint are pretty rare and will have a higher premium over their counterparts. The Carson City Mint (CC) operated intermittently between 1870 and 1893 and struck relatively fewer coins compared to other mints like Philadelphia, San Francisco, and New Orleans. The most commonly counterfeited coins are those issued by the San Francisco and Carson City mints.
