The Legacy of the 1878-CC Morgan Dollar
The 1878-CC Morgan Dollar stands as a testament to America’s westward expansion and the silver mining boom that defined the era. Struck at the historic Carson City Mint in Nevada, this coin marks the inaugural year of George T. Morgan’s now-legendary design. The Carson City facility, operating from 1870 to 1893, produced these silver dollars during Nevada’s Comstock Lode heyday, making them prized possessions for collectors fascinated by Western Americana and America’s territorial growth.
With a mintage of roughly 2.2 million pieces, the 1878-CC isn’t the rarest Carson City Morgan, but its historical significance and connection to a short-lived mint keep demand strong. The distinctive “CC” mint mark, positioned below the wreath on the reverse, serves as the coin’s signature and a crucial identifier for authentic specimens.
Authentication: The Collector’s First Defense
Weight, Dimensions, and Metallic Composition
Genuine 1878-CC Morgan Dollars should weigh exactly 26.73 grams with a diameter of 38.1mm. The 90% silver, 10% copper alloy gives these coins their characteristic heft and distinctive ring—qualities counterfeiters struggle to duplicate. Always verify weight using a precision scale that measures to at least one-tenth of a gram for accurate results.
The Magnet Test: Simple but Effective
Since authentic Morgan Dollars contain 90% silver, they should show no magnetic attraction. This straightforward test can immediately expose many modern counterfeits, particularly those made with magnetic base metals or steel cores plated with silver. However, sophisticated fakes using non-magnetic alloys can still pass this test, so it’s just one tool in your authentication arsenal.
Die Characteristics and Strike Quality
The 1878-CC Morgan Dollar exhibits several distinctive die characteristics that experienced collectors use for authentication. Liberty’s profile shows specific hair detail and cotton blossom elements on the obverse, while the reverse displays precisely rendered eagle feathers and the correctly positioned “CC” mint mark below the wreath.
Original Carson City Morgans typically display strong central details with slightly softer areas near the rims—a byproduct of the striking pressure used at the facility. The edge should feature exactly 177 reeds, evenly spaced and well-defined, contributing to the coin’s overall eye appeal.
Surface Features and Natural Toning
Authentic 1878-CC dollars often display natural toning that developed over more than a century. Original coins may show rainbow hues, golden toning, or even dark carbon spots—imperfections that are extremely difficult to replicate artificially. Under proper lighting, the surface should exhibit consistent luster, with toning that appears gradual rather than abrupt or artificially applied.
Counterfeit Detection: Know Your Enemy
Cast Counterfeits: The Amateur’s Approach
Many fake 1878-CC dollars are created through casting methods, which leave telltale surface characteristics. Look for bubbles or porosity in the metal, particularly in recessed areas. Cast coins typically lack the sharp detail of genuine struck specimens, and surfaces may appear grainy or uneven when examined under magnification.
Altered Mint Marks: A Common Deception
One of the most prevalent counterfeiting methods involves taking common-date Morgan Dollars and adding a “CC” mint mark. Examine the mint mark carefully under magnification. Authentic “CC” punches display specific characteristics in the serifs and spacing that are nearly impossible to replicate accurately. The mint mark should appear slightly raised and naturally integrated with the surrounding surface—not added later.
Transfer Die Fakes: The Sophisticated Threat
More advanced counterfeits employ transfer dies created from genuine coins, allowing for excellent detail reproduction. These can be particularly challenging to detect. However, transfer dies often show slight softening of the finest details and may lack the crispness of original dies. The surface texture might also differ subtly from authentic coins.
Authentication Methods: A Systematic Approach
Visual Examination: The Collector’s First Line of Defense
Begin with a thorough visual inspection using a 10x loupe or microscope. Check for:
- Sharpness of detail in high points like Liberty’s hair and the eagle’s feathers
- Consistency of the edge reeding
- Quality and integration of the mint mark
- Surface texture and luster characteristics
- Any signs of casting bubbles or porosity
Specific Gravity Testing
The specific gravity test provides another authentication layer. Since silver has a specific gravity of 10.49 and copper 8.96, a 90% silver coin should measure around 10.3. This test requires a precision scale and water displacement setup but can help identify coins with incorrect metal composition.
Professional Authentication Services
For high-value specimens or when uncertainty remains, professional authentication services like PCGS, NGC, ANACS, or ICG offer expert examination. These services employ advanced techniques including X-ray fluorescence analysis to determine metal composition and microscopic examination to identify die characteristics and potential alterations.
Toning, Cleaning, and Preservation
Understanding Natural Toning
Natural toning on silver coins develops over decades through exposure to sulfur compounds in the air. This creates distinctive patterns that are extremely difficult to replicate artificially. Original toning often shows rainbow colors or golden hues that gradually transition across the coin’s surface.
Carbon Spots: The Collector’s Dilemma
Carbon spots, like those discussed in collector forums, are common on Morgan Dollars and notoriously difficult to remove without damaging the coin. These spots typically result from contaminants on the planchet before striking and become embedded in the metal. As experienced collectors note, these spots often cannot be removed through dipping without leaving noticeable damage that affects the coin’s numismatic value.
Cleaning Considerations
Collector forums highlight important considerations about dipping Morgan Dollars. Quick, light dips may remove some toning but risk stripping natural luster. The consensus among experienced collectors is that aggressive cleaning often does more harm than good, potentially reducing the coin’s value more than the original toning issue.

Final Thoughts: The Collector’s Responsibility
The 1878-CC Morgan Dollar remains one of the most desirable coins in American numismatics, combining historical significance with relative availability. However, the popularity of Carson City issues has made them frequent targets for counterfeiters. By understanding the specific diagnostic points discussed in this guide—weight, magnetic properties, die markers, and common counterfeiting methods—collectors can better protect themselves from acquiring fake specimens.
Remember that authentication is both an art and a science. While the tests and observations outlined here provide a solid foundation, developing expertise requires study, experience, and often consultation with more experienced collectors or professional authenticators. When dealing with valuable specimens, don’t hesitate to seek professional opinions before making significant purchases.
The forum discussions about toning and cleaning decisions also highlight an important principle in coin collecting: originality often trumps perfection. Many experienced collectors prefer coins with natural toning and minor imperfections over cleaned or altered specimens, even if the latter appear more attractive at first glance. This preference for originality has strengthened over recent decades as the numismatic community has become more educated about preservation and authentication issues.
Whether you’re a seasoned collector or just beginning your journey into Morgan Dollars, understanding these authentication principles will serve you well in building a quality collection of genuine, historically significant coins that will be treasured for generations to come.
