The 1900-O/CC Morgan Dollar is worth anywhere from $30 in heavily worn condition to well over $500 in mint state — and certain high-grade examples have sold at auction for thousands of dollars. If you’ve stumbled across one of these silver dollars in an old collection or estate sale, you may be holding something truly special.
What Makes the 1900-O/CC Morgan Dollar So Unusual
The “O/CC” mintmark on this coin tells a fascinating story. It means the coin was struck at the New Orleans Mint in 1900, but the die used had originally been prepared for the Carson City Mint — the “CC” mintmark was repunched with an “O” on top, leaving traces of the old “CC” visible beneath.
This kind of mintmark variety is called an overmintmark, and collectors absolutely love them. The 1900-O/CC is one of the most recognized overmintmark varieties in the entire Morgan Dollar series. It was listed in the Red Book for decades and remains a staple of 19th-century American numismatics.
Unlike a common date Morgan Dollar that might be worth only melt value, this variety carries a meaningful premium simply because of that double-stamped mintmark. Even in circulated condition, it tends to sell for more than a standard 1900-O.
If you’re not sure whether the coin you have is the O/CC variety or a regular 1900-O, a good coin identifier and value app can help you examine the mintmark details and get a preliminary identification right from your phone.

How to Tell If Your Coin Is the O/CC Variety
This is the million-dollar question — or at least the few-hundred-dollar question. The distinction between a regular 1900-O and the 1900-O/CC can be subtle, especially on worn coins.
To spot it, look closely at the mintmark on the reverse side of the coin, just above the “DO” in DOLLAR at the bottom. On the O/CC variety, you’ll see faint remnants of the Carson City “CC” mintmark peeking out from behind the “O.”

You’ll need magnification — a 5x to 10x loupe or a coin microscope works well. The traces of “CC” appear as two small curved bumps or bars visible at the lower edges or sides of the “O.”
CoinKnow is an excellent tool for collectors dealing with exactly this kind of variety identification challenge. The app provides detailed variety data and high-resolution images that help you compare your coin’s mintmark to known examples of the 1900-O/CC.
What Affects the Value of Your 1900-O/CC Morgan Dollar
Beyond grade, several other factors influence how much a buyer will pay for your coin.

Luster and eye appeal matter enormously in the mint state range. Two coins graded MS-63 can sell for very different prices depending on the quality of their surfaces. A coin with deep, cartwheel luster and minimal bag marks will always outperform a technically equal coin that looks dull or heavily marked.
Original skin — meaning the coin hasn’t been cleaned or polished — is critical. Cleaned coins are significantly discounted by dealers and collectors alike. If your coin has been wiped down or dipped in solution, expect the value to drop noticeably even if it still looks shiny.
Third-party grading by services like PCGS or NGC adds legitimacy and can substantially increase what a buyer is willing to pay. A raw (ungraded) 1900-O/CC selling for $120 in VF might fetch $160 or more once it’s been slabbed and authenticated.

Should You Sell, Hold, or Get It Graded
If you’ve confirmed you have the O/CC variety in a decent grade, you’re in a good position. This is not a common junk-box coin — it has real collector demand and a story behind it.
For circulated examples in Good to Very Fine, selling to a reputable dealer or through an online platform like eBay is perfectly reasonable. You’ll get fair market value without the cost of grading eating into your profit.
For coins in AU or better, professional grading is almost always worth the investment. The authentication protects you as a seller and reassures buyers, especially at higher price points. CoinKnow can help you estimate whether your coin’s grade warrants the submission fee before you commit.
For anything that might be gem mint state — minimal marks, bold luster, sharp strike — hold onto it until you can get an expert opinion or have it evaluated by a major grading service. Gem examples are genuinely rare and can bring serious money from advanced collectors.

FAQ
Q: How do I know if my Morgan Dollar is the 1900-O/CC variety?
A: Look at the “O” mintmark on the coin’s reverse under magnification. On the O/CC variety, you’ll see traces of the original “CC” (Carson City) mintmark showing through beneath the “O.” Apps like CoinKnow offer variety comparison tools that make this identification process much easier.
Q: Is the 1900-O/CC Morgan Dollar silver?
A: Yes. Like all Morgan Dollars, it’s composed of 90% silver and 10% copper, weighing 26.73 grams. Even at melt value, it contains about 0.7734 troy ounces of pure silver — but the variety premium means it’s almost always worth significantly more than its silver content alone.
Q: How rare is the 1900-O/CC Morgan Dollar?
A: It’s not extremely rare in absolute terms — millions of Morgan Dollars were minted at New Orleans in 1900 — but the O/CC variety is a recognized subset of that mintage, and examples in higher grades are genuinely scarce. It’s a popular variety with consistent collector demand, which keeps prices strong across all grade levels.
