1856 G50C BG-311a (Regular Strike)
Obverse & Reverse
The 1856 Octagonal Gold 50 Cents, cataloged as Breen-Gillio 311a, represents the twilight of the initial, utilitarian phase of California Fractional Gold. These fascinating and diminutive coins were born of necessity from the chaos of the California Gold Rush. Following the discovery of gold at Sutter's Mill in 1848, an immense wave of over 300,000 prospectors and entrepreneurs descended upon California. This population explosion created a vibrant, cash-rich economy, but one critically deficient in circulating small change. Federal coinage was scarce on the isolated West Coast, and the U.S. Branch Mint in San Francisco would not be fully operational until the mid-1850s. To bridge the gap, merchants and miners resorted to using pinches of gold dust for minor transactions—an inaccurate and contentious system. Seeing a commercial opportunity, numerous private jewelers and metallurgists in San Francisco began striking their own small-denomination gold coins in quarter dollar, half dollar, and dollar values starting in 1852. These 'Period One' (1852-1857) issues, including the BG-311a, were generally intended to contain their face value in gold and were accepted, albeit unofficially, in local commerce. They were typically hand-struck, resulting in crude but charming pieces. By 1856, the year of this coin's issue, the San Francisco Mint was beginning to alleviate the small-change crisis with federal silver coins, reducing the need for private issues. Consequently, production of fractional gold waned, making the 1856-dated pieces among the last of their kind intended for actual circulation. The BG-311a is a variety of the BG-311 die pairing, and its immense rarity suggests it may have been a trial or transitional striking. Its existence is a testament to the decentralized and entrepreneurial nature of money creation on the American frontier before the federal government fully consolidated its control over coinage with the Private Coinage Act of 1864.
Associated EventCalifornia Gold Rush
Reason For MintingTo alleviate a severe shortage of small denomination coinage for daily commerce in Gold Rush-era California.
Minter HistoryThe minter of BG-311a, like many Period One California Fractional Gold issuers, is unknown. The work was often performed by jewelers who did not sign their products, in part to avoid potential legal issues and also because the focus was on utility rather than brand. Prominent jewelers of the era known to have produced fractional gold include Antoine Louis Nouizillet, M. Deriberpe, and the firm of Frontier & Deviercy, but a definitive link to this specific variety has not been established.
Historical SignificanceAs a 'Period One' issue, this coin is a tangible artifact from the height of the California Gold Rush, representing a private solution to a government failure in supplying adequate currency. Its 1856 date marks the end of the era where these coins were truly necessary for commerce, making it a bookend to a fascinating chapter in American monetary history. The extreme rarity of the BG-311a variety elevates it to a near-mythical status within the specialized field of California Fractional Gold.

Rarity ScaleR-9 (Unique or Nearly Unique)
The BG-311a is a numismatic ghost of the highest order. Its appeal lies in its legendary rarity as a nearly unique variety of a popular and historically significant series. For the advanced specialist of California Fractional Gold, owning a BG-311a would be a pinnacle achievement, representing one of the rarest of all 'Period One' business strikes.
Key VarietiesThe primary variety is the BG-311, which is itself scarce (R-5). The BG-311a is a distinct die variety of which only two specimens have been reported. Crucially, collectors should be aware of a later, special collector issue: the BG-915A. The BG-915A is a circa 1860 restrike of the 1856-dated octagonal BG-311 dies. It is distinguished from original strikes by having a plain edge and being struck on a gold-plated, baser-gold planchet.
Authentication TipsDue to its extreme rarity, any example claiming to be a BG-311a requires authentication by top-tier experts and grading services. Authentication would rely on a direct comparison to the known genuine examples. General tips for Period One fractionals apply: look for a business-strike appearance, not a prooflike souvenir finish. The gold should be of a slightly pale, silvery color consistent with unrefined California gold. Replicas are common; they are often brassy, have incorrect weights, exhibit casting evidence (pits, seams), or feature crude, cartoonish details unlike the Longacre-inspired originals. Lettering and stars on genuine pieces, while sometimes crudely executed, are typically sharp from the die.
Shopping ConsiderationsAcquiring a BG-311a is a matter of opportunity, not choice; it would likely only trade via a major auction of a landmark collection. Should one appear, a potential buyer should focus entirely on its authenticity and provenance. For the more obtainable BG-311, a premium quality example would be one that is well-centered and sharply struck, particularly on Liberty's hair and the wreath details. Original, uncleaned surfaces are paramount. Many fractionals were used as jewelry and show evidence of mounting, solder, or harsh cleaning, all of which should be avoided. A coin with original reddish-gold toning and minimal distracting marks would command a significant premium.
A coin's grade is its condition, rated on a 1-70 scale. For rare coins, this is the most critical factor in determining value, as a tiny difference in preservation can mean a huge difference in price.
Relevant Grade TypesOriginal period issues like the BG-311a were business strikes intended for circulation, thus they are found in Circulated (1-58) and Mint State (MS, 60-70) grades. No proofs were struck during the original minting period. However, a later collector issue, the BG-915A restrike of the BG-311, exists. This is a separate numismatic item and is not an original proof, but was made for numismatic purposes after the fact.
Mint State CharacteristicsAn uncirculated example would be judged on the quality of its strike and luster. These were manually struck, so weakness in some areas, such as the centers, is common. The highest quality pieces would show sharp details in Liberty's coronet and hair strands, and clear definition in the wreath leaves on the reverse. The luster on these issues is typically soft and satiny, not deeply prooflike. Small planchet flaws or adjustment marks made prior to striking are common for the series and may not detract significantly from the grade unless they are severe.
Circulated Wear PatternsWear first appears on the highest points of the design. On the obverse, this includes Liberty's cheek, the hair above the eye, and the coronet. On the reverse, the high points of the wreath leaves and the bow would show the first traces of friction. In lower grades (VG and below), the stars will begin to merge with the border and the finer details of the wreath will be completely effaced.
Key Factors For ValueFor a legendary rarity like BG-311a, authenticity and provenance are the paramount drivers of value. Beyond that, the primary factor is surface preservation. An example with original, uncleaned 'skin' is vastly superior to one that has been polished or cleaned, even if the latter shows less wear. Strike quality is secondary but important; a sharply struck coin is always preferred. Eye appeal, driven by attractive toning and a lack of distracting marks, plays a significant role. Given the prevalence of counterfeits in this series, a CAC sticker on a certified example provides an additional layer of confidence and would likely result in a substantial price premium.
