History of the 1900-O New Orleans Morgan Dollar

The 1900-O Morgan Silver Dollar was struck at the legendary New Orleans Mint during a time of immense economic transition in the United States. New Orleans coins are often distinguished by the small “O” mint mark located on the reverse side. In the late 19th century, silver dollars were the backbone of commerce in the American South and West, representing hard currency you could feel in your palm.

Identifying your coin is the first step toward understanding its potential. Many beginners find it helpful to use a top coin identifier and value app to confirm the mint mark and date accurately. The 1900-O is particularly interesting because over 12 million of them were minted, making them accessible to modern collectors while still retaining great value in better conditions.

Because many of these coins were stored in Treasury bags for decades, they often exhibit “bag marks”—tiny nicks from clashing against other coins. Finding one without these marks is what leads to the massive price jumps you see in professional auctions. To get a better sense of rarity, many hobbyists use CoinKnow to browse high-definition images of top-tier grades.

How to Identify the 1900-O Mint Mark

Before you get excited about the price, you need to be sure your coin was actually minted in New Orleans. The 1900 Morgan Dollar was produced at three different locations: Philadelphia (no mint mark), San Francisco (S), and New Orleans (O). The “O” mint mark is located on the reverse (tails) side of the coin, just above the letters “D” and “O” in the word “DOLLAR.”

If your coin has no letter there, it’s a Philadelphia minting, which has a slightly different value profile. The New Orleans Mint was known for sometimes producing “weak strikes,” where the details on Lady Liberty’s hair or the eagle’s breast feathers aren’t as crisp as coins from other mints. This makes a sharply detailed 1900-O even more valuable to a dedicated numismatist.

When evaluating your coin, checking the 1900 silver dollar value often reveals that the New Orleans Mint was one of the most prolific producers of the era. However, “bag toning”—the colorful oxidation that happens to silver over time—can drastically increase the appeal and price of a New Orleans dollar.

Grading and Condition: Why It Matters

In the world of coin collecting, condition is everything. A 1900-O Morgan Dollar that spent years in a cowboy’s pocket will be worn smooth and worth mostly its silver content plus a small premium. However, a coin that was tucked away in a bank vault and never touched can be worth thousands. Coins are graded on a scale from 1 to 70.

A grade of “Good” (G4) means the coin is very worn, while “Mint State” (MS60 and up) means the coin has no wear from circulation. Even a single point difference in grade can mean a difference of hundreds of dollars. For instance, the 1900-O Morgan Dollar price in MS condition can skyrocket if the coin reaches the “Gem” level of MS65.

Grade Detail	Visual Characteristics
Very Good (VG8)	Main features visible but flat; rims are clear.
Extremely Fine (XF40)	Light wear on high points; hair lines are visible.
About Uncirculated (AU50)	Traces of wear only on eagle’s breast and Liberty’s cheek.
Mint State (MS63)	Full luster but with some distracting marks or scuffs.
Mint State (MS65)	Strong luster; very few marks; excellent eye appeal.

The Rare 1900-O/CC Error Variety

One of the most exciting aspects of the 1900-O Morgan Dollar is the “O over CC” variety. This happened when the New Orleans Mint reused dies originally intended for the Carson City (CC) Mint. If you look closely at the mint mark with a magnifying glass, you might see the faint remnants of two “C”s underneath the “O.”

This variety is highly sought after by specialists. Because the Carson City mint is legendary for its low production and “Wild West” history, any coin featuring its mark—even a recycled one—commands a high premium. Using CoinKnow‘s magnification tools can help you spot these tiny details that might turn a $50 coin into a $500 treasure.

If you suspect you have an O/CC variety, do not try to clean the coin! Cleaning a silver dollar actually destroys its numismatic value. A natural patina is always preferred by collectors. Instead, compare your coin to known error samples to see if the mint mark looks “doubled” or unusually thick.

Coin Variety	Approximate MS63 Value	Approximate MS65 Value
Standard 1900-O	$110	$400
1900-O/CC Variety	$1,000	$4,500+

Silver Content and Intrinsic Melt Value

Even if your 1900-O Morgan Dollar is in poor condition, it still has “intrinsic” value because of its silver content. Every Morgan Silver Dollar is composed of 90% silver and 10% copper. Specifically, each coin contains approximately 0.77344 troy ounces of pure silver.

This means the price of your coin will never drop below the “melt value.” For example, if silver is trading at $25 per ounce, your coin has about $19 worth of raw silver inside it. However, because Morgan Dollars are so popular, they almost always sell for a “collector premium” above this melt price.

Currently, even the most battered 1900-O Morgan Dollars usually sell for at least $30 to $35 at local coin shops. If you find a buyer offering less than that, they are likely trying to buy beneath the scrap silver value.

Where to Sell Your 1900-O Silver Dollar

Once you’ve identified the grade and whether or not you have an error variety, you might decide to sell. You have several options, ranging from local coin shops to large online auction houses. For coins worth under $100, a local dealer or eBay is often the easiest route.

For high-grade coins (MS65 or higher) or the O/CC variety, you should consider having the coin “certified” by a professional grading service like PCGS or NGC. A certified coin provides a guarantee of authenticity and grade, which makes it much easier to sell for its full market value. Buyers are much more willing to pay thousands of dollars for a coin that is sealed in a plastic “slab” with a verified grade.

Remember to document your coin well. Take clear photos of both sides in natural light. Avoid using a flash, as it can hide the coin’s true luster or exaggerate scratches. A well-presented 1900-O Morgan Dollar will always attract more interest from serious collectors.

Selling Method	Best For…	Pros/Cons
Local Coin Shop	Quick cash, lower-value coins	Fast, but may offer wholesale prices.
Online Auctions	Reaching many collectors	Higher potential price; requires shipping and fees.
Major Auction Houses	Rare errors and high grades	Best for $1,000+ items; takes time.

FAQ

Q: Why is the New Orleans Mint mark “O” so significant?

A: The New Orleans Mint was the only Southern mint to produce Morgan Dollars. It closed in 1909, making coins with the “O” mint mark nostalgic pieces of Southern history. Specifically, the 1900-O is known for its wide variety of strikes and the famous O/CC error.

Q: Is my 1900-O Morgan Dollar real or a fake?

A: Counterfeits exist, especially for silver dollars. A genuine 1900-O should weigh exactly 26.73 grams and have a diameter of 38.1 mm. It should also be magnetic—if a magnet sticks to your coin, it is definitely a fake. Using a scale and a caliper is the best way to verify it at home.

Q: Should I clean my silver dollar to make it look shiny?

A: No! Never clean your coins. Cleaning causes microscopic scratches on the surface that professional graders can easily spot. A “cleaned” coin can lose 50% or more of its collector value compared to an uncleaned coin with natural aged patina.

Q: How many 1900-O Morgan Dollars were made?

A: There were 12,590,000 of these coins struck at the New Orleans Mint in 1900. While this is a high number, many were melted down under the Pittman Act of 1918, which is why they remain valuable today.

Q: What is the most expensive 1900-O ever sold?

A: While average coins sell for under $100, a 1900-O Morgan Dollar in a nearly perfect MS67 grade can sell for over $30,000 at a high-end auction because so few survived in that pristine condition.
