1870-CC Seated Liberty Dollar: The First Carson City Rarity Collectors Prize

When the Carson City Mint opened in 1870, it marked a pivotal moment in American monetary history. Nevada's Comstock Lode silver mines were pouring out ore in unprecedented quantities, and the government needed a mint in the region to convert that raw material into coinage. The first coins struck at Carson City in 1870 are now among the most historically significant and collectible coins in all of American numismatics. Among them, the 1870-CC Seated Liberty Dollar occupies a place of particular distinction.

Historical Context

The Carson City Mint (identified by the "CC" mintmark) opened officially on February 11, 1870. Located in Carson City, Nevada, it was strategically positioned to process the enormous silver output of the Comstock Lode mines. The mint's construction had been controversial and delayed, but once operational, it began producing coins that would serve the western United States and the Pacific trade.

The Seated Liberty dollar design, introduced in 1840, was already 30 years old by 1870. It features Liberty seated on a rock, holding a shield and a staff topped with a Liberty cap, designed by Christian Gobrecht. This was the dollar design in use when Carson City began its production.

The 1870-CC is significant as one of the very first coins struck at the new mint. The mintage of 11,758 pieces was small by any standard, representing less than a single day's output at major mints during peak production periods. Carson City was still establishing its procedures, workforce, and supply chains in 1870.

The Mintage and Survival Rate

Of the 11,758 coins originally struck, relatively few have survived in collectible condition:

Why so few survived:

• Silver dollars of this era circulated heavily in the western US and Pacific trade

• Many were melted during subsequent silver purchases and monetary policy changes

• Storage before the advent of protective coin holders meant that circulating examples suffered significant wear

• The Carson City Mint didn't have the institutional weight of Philadelphia or San Francisco, so preservation of examples wasn't a priority

NGC and PCGS combined have certified several hundred examples in all grades, with the majority grading below VF-20. True mint state examples are extraordinarily scarce.

Current Market Values

Grade	Approximate Value
AG-3 (About Good)	$400 - $700
G-4/6 (Good)	$700 - $1,200
VG-8/10 (Very Good)	$1,200 - $2,500
F-12/15 (Fine)	$2,500 - $5,000
VF-20/30 (Very Fine)	$5,000 - $12,000
EF-40/45 (Extremely Fine)	$12,000 - $30,000
AU-50/58 (About Uncirculated)	$30,000 - $80,000
MS-60/62 (Mint State)	$80,000 - $200,000
MS-63+	Genuinely rare, auction record territory

These values reflect certified (NGC or PCGS) coins. Raw examples sell at meaningful discounts to certified coins due to authentication and grading uncertainty.

Grade Definitions for This Coin

About Good (AG-3): Heavily circulated with only the major design elements visible. Date and mintmark readable. While this sounds like poor condition, a 150-year-old coin with an 11,758 mintage that has survived at all is genuinely collectible.

Good (G-4/6): Flat but complete design outline. Date clear, CC mintmark present and identifiable. The most affordable entry point for new collectors of this date.

Very Good (VG-8/10): Major details clear, some design elements showing. Liberty's gown visible with some separation of lines.

Fine (F-12/15): Moderate wear on high points with major design elements clear. A respectable collector grade for this rarity.

Very Fine (VF-20/30): Light to moderate wear with most design elements sharp. The CC mintmark is fully clear and well-defined. Desirable for serious collectors.

Extremely Fine (EF-40/45): Only light wear on the very highest points. Sharp, detailed appearance. This is where the coin starts to become a genuine showpiece.

About Uncirculated (AU-50/58): Traces of circulation, but mostly original mint luster remaining. These coins are extraordinarily difficult to find and represent a major acquisition.

Mint State: Almost no examples have been certified in high mint state. Those that exist command prices that reflect their exceptional rarity.

The CC Mintmark: Key Identifying Feature

For collectors, the CC mintmark is the defining characteristic of this coin. Located on the reverse between the eagle's tail feathers and the "DOL" in "DOLLAR," the mintmark must be:

• Clear and legible: Weak or partially visible CC marks should be examined carefully

• Original position: In the correct location for 1870 production

• Not altered: Some counterfeiters have attempted to add CC mintmarks to common Philadelphia (no mintmark) examples

For any coin claiming to be 1870-CC, authentication by PCGS or NGC is essentially mandatory before serious financial transactions. The difference between a genuine 1870-CC and a 1870 Philadelphia example is the entire value premium.

Carson City Dollars as a Collection

The 1870-CC is the first coin in what is known as the "CC dollar" series, spanning from 1870 to 1885. Completing this series in all dates and grades is a significant undertaking that occupies some of the most serious numismatists in the hobby. Key dates include:

• 1870-CC (first issue)

• 1873-CC (a major rarity, especially in high grade)

• 1874-CC

• 1876-CC (high mintage but worn examples common)

• 1878-CC

• 1885-CC (famous rarity, most in government storage)

The 1870-CC as the "first" of this series gives it additional emotional and historical weight for completist collectors.

Authentication Notes

Several important authentication points specific to this coin:

1870 Philadelphia coins (no mintmark) were also struck and are common. An 1870 Philadelphia dollar with an added CC mintmark is the most likely form of counterfeit. Under proper magnification, genuine mintmarks show consistent die characteristics, while added mintmarks may show evidence of soldering, tooling, or inconsistent metal color.

Coin doctors sometimes alter severely damaged examples to improve appearance. Look for evidence of cleaning (microscopic parallel scratches called hairlines), smoothing, or artificial toning.

Third-party grading (PCGS or NGC) solves all these authentication concerns for serious buyers. A PCGS or NGC certified 1870-CC is what serious collectors should seek.

Investment Perspective

The 1870-CC Seated Liberty Dollar has demonstrated consistent appreciation over decades of the numismatic market. The combination of historical significance (first CC issue), genuine low mintage, and strong collector demand from multiple constituencies (Carson City specialists, Seated Liberty specialists, type collectors, US dollar specialists) creates durable value support.

Entry-level examples in Good condition are accessible and have appreciated steadily. High-grade examples represent significant investments but have historically appreciated faster than lower-grade counterparts.

Final Thoughts

The 1870-CC Seated Liberty Dollar is a genuine piece of American monetary history. The Carson City Mint's opening was a significant event in western expansion and the monetization of Nevada's silver wealth, and this coin is the physical artifact of that moment. Whether you're building a CC series collection, a Seated Liberty type set, or simply want a historically significant 19th-century American coin, the 1870-CC earns its place as one of the most meaningful acquisitions a numismatist can make.
