Where Is the Mint Mark on a 1900 Silver Dollar?
Locating exactly where is the mint mark on a 1900 silver dollar is the first crucial step every coin collector, estate executor, or antique enthusiast must take to determine the true scarcity and market value of this historic coin. The 1900 silver dollar is a beloved entry in the iconic Morgan Silver Dollar series, designed by United States Mint Chief Engraver George T. Morgan and minted between 1878 and 1904 (and once more in 1921). Struck in ninety percent fine silver and ten percent copper, these heavy silver cartwheels carry a rich numismatic heritage. While the front (obverse) of the coin proudly displays the profile of Lady Liberty surrounded by stars and the year 1900, the vital mint mark is located exclusively on the back (reverse) of the coin, positioned in a specific focal zone right above the denomination lettering.
Precise Reverse Mint Mark Location and Facility Letters
To find the mint mark on a 1900 Morgan silver dollar, flip the coin over to its reverse side. In the center of the coin, you will see a heraldic bald eagle with outstretched wings clutching an olive branch and arrows within an open laurel wreath. Look directly below the tied ribbon bow of the laurel wreath and just beneath the tail feathers of the eagle. In the narrow open space between the ribbon bow and the words 'ONE DOLLAR'—specifically centered directly above the letters 'D' and 'O' in 'DOLLAR'—you will find the small stamped mint mark letter.
In 1900, the United States Mint produced Morgan silver dollars at three different operating mint facilities: Philadelphia, New Orleans, and San Francisco. If you examine the space above 'DOLLAR' and see no letter at all, your coin was struck at the main United States Mint in Philadelphia. If you observe a crisp, stamped letter 'O', your dollar was minted in Louisiana at the historic New Orleans Mint. If you find a stamped letter 'S', the coin originated from the San Francisco Mint in California. Identifying which facility struck your 1900 dollar dramatically impacts its rarity and collector value.
Review the mint marks, manufacturing facilities, total production mintages, and typical collector values for the 1900 Morgan dollar below:
| Mint Mark Stamping | Mint Facility & Location | Original Mintage Volume | Typical Circulated to Mint State Value |
|---|---|---|---|
| No Mint Mark (Plain) | Philadelphia Mint (Pennsylvania) | 8,830,000 struck | $32 to $55 (Circulated) / $75 to $250 (MS63–MS65) |
| 'O' Mint Mark | New Orleans Mint (Louisiana) | 12,590,000 struck | $32 to $50 (Circulated) / $70 to $220 (MS63–MS65) |
| 'S' Mint Mark | San Francisco Mint (California) | 3,540,000 struck (Scarce) | $45 to $160 (Circulated) / $450 to $2,500+ (MS63+) |
| 'O' Over 'CC' (Micro-Variety) | New Orleans Mint (Reused CC Die) | Included in 1900-O mintage | $120 to $350 (Circulated) / $600 to $3,000+ (MS63+) |
| Proof Striking (No Mint Mark) | Philadelphia Mint (Special mirror finish) | 912 struck exclusively for collectors | $3,500 to $12,000+ depending on grade |
The 1900-S has the lowest regular business strike mintage among the three mints, making it significantly more valuable in uncirculated grades.
The Famous 1900-O Over CC Variety, Grading, and Authentication
One of the most thrilling discoveries in numismatics centers on the 1900-O Morgan dollar. In 1893, the United States Government closed the famous Carson City Mint in Nevada. In 1900, mint officials shipped unused, obsolete reverse dies originally prepared with the 'CC' mint mark from Carson City down to the New Orleans Mint. New Orleans engravers punched an 'O' mint mark directly over the existing 'CC' letters. Using a 10x jeweler's loupe, astute collectors can inspect the 'O' mint mark; if you see the faint, ghostly curves of the top and bottom of two 'C's protruding from inside or behind the 'O', you have discovered the valuable '1900-O Over CC' variety (VAM-11 or VAM-12).
When examining your 1900 silver dollar, never clean or polish the coin using silver dips, baking soda, or polishing cloths. Harsh abrasive cleaning creates microscopic hairline scratches and strips the original cartwheel mint luster, instantly destroying up to eighty percent of the coin's numismatic collector premium. Authentic Morgan dollars weigh exactly 26.73 grams, measure 38.1 millimeters in diameter, and have a reeded edge with precisely counted ridges. Verifying weight on a digital jeweler's scale is a quick way to screen out lightweight modern counterfeit copies made from base metals.
Review the official physical specifications and numismatic standards for authentic 1900 Morgan silver dollars in the table below:
| Physical Specification | Official US Mint Standard | Tolerable Variance | Numismatic Authentication Purpose |
|---|---|---|---|
| Total Weight | 26.73 Grams (0.859 Troy Ounces) | +/- 0.09 Grams (slight wear) | Detects cast iron, zinc, or silver-plated counterfeit fakes |
| Precious Metal Composition | 90% Silver, 10% Copper alloy | Exact chemical metallurgy | Yields 0.77344 troy ounces of pure silver melt value |
| Coin Diameter | 38.1 Millimeters (1.50 Inches) | Precise outer rim diameter | Verifies original coin collar dimensions |
| Edge Construction | Reeded Edge (Grooved ridges) | Uniform milled serrations | Historically prevented fraudulent metal shaving/clipping |
| Mint Mark Position | Reverse above 'DO' in 'DOLLAR' | Centered beneath bow ribbon | Differentiates Philadelphia, New Orleans, and San Francisco |
Submitting scarce or high-grade coins to third-party grading services like PCGS or NGC guarantees authenticity and maximizes resale liquidity.

Inspect with a 10x Jeweler's Loupe
Use a magnification loupe under strong incandescent lighting to identify an 'O', an 'S', no letter (Philadelphia), or an 'O over CC' variety.
