1921 was the last year that Morgan silver dollars were produced by the United States Mint. However, a 1921 Morgan is not a very rare coin, as over 65 million coins were produced. Despite their limited amount of rarity, they are still worth money to numismatists and investors as they are composed of 90 percent silver. The better the condition your coin is in, the more it is worth to collectors.
Examine your Morgan and determine its condition. Coins are graded on a 70 point scale, with a 70 being a flawless coin and a grade of 1 referring to a coin that can barely be identified. Refer to a grading scale and determine an estimated grade for your Morgan silver dollar.
Refer to a coin price guide to get an estimated value for your Morgan. PCGS, a profession coin grading company offers a free guide you can use to reference your coin. NGC, another professional grading service, offers a free guide, but you must create an account on their website to access it. These prices are only estimates and will not give you the true market value of your 1921 Morgan silver dollar.
Photograph your 1921 Morgan from different angles. You want to capture the condition your coin is in by showing scuffs, dings and wear. Additionally, you should photograph your Morgan in different lights to show the amount of luster it has.
Determine where you want to sell your 1921 Morgan. Since it is not a rare coin unless it is in pristine condition, taking it to a local dealer will likely not be your best option. Selling it online on sites such as eBay should earn you the most money. However, you can also use a search engine to find coin collector forums and see if anyone is interested in buying Morgans.
Create a description of your coin. You should describe the condition of the coin in addition to showing potential buyers the photographs you took.
Determine your selling price and post all of the relevant information about your Morgan. If selling on eBay, the auction format will likely generate a fair market value based on the condition of the coin, so don't worry about determining the correct price; simply let the auction run its course.
