Description

Cataloged as BG-922 in the Breen-Gillio reference, this 1870 octagonal California gold half dollar measures approximately 13 to 14 millimeters in diameter — roughly the size of a modern dime. Produced during the later period of California fractional gold coinage, this piece reflects the continued market for small gold coins on the Pacific Coast, whether for everyday transactions, souvenirs, or the jewelry trade. This piece displays the characteristic Liberty Head obverse typical of its Breen-Gillio catalog group, with the denomination indicated on the reverse. The die engraving on California fractional gold pieces, while necessarily simplified by the small planchet size, often exhibits surprising detail and craftsmanship given the constraints of the medium. The octagonal format is one of the distinctive hallmarks of California fractional gold coinage, distinguishing these pieces from conventional round coins and adding visual interest that has long attracted collectors. The later period of California fractional gold production, spanning roughly 1859 through 1882, saw a gradual shift in purpose. As the San Francisco Mint and branch mints increased production and federal small-denomination coinage became readily available on the Pacific Coast, the purely economic rationale for fractional gold diminished. Production continued, however, driven by tourist demand, collector interest, and the jewelry trade — these tiny gold coins made attractive ornamental pieces and souvenir items, and many surviving examples show evidence of having been mounted as jewelry.

Rarity Notes

Moderately available. While California fractional gold as a class is uncommon by general numismatic standards, Period Two issues are among the more accessible entries in the series.
