Half Dollar Octagonal, Period 2 (BG-901 to BG-999)

About This Coin

Spanning BG numbers 901 through 999 in the Breen-Gillio catalog, these Period 2 octagonal gold half dollars represent the later production phase of California fractional gold coinage, primarily from the 1870s and early 1880s when these diminutive gold pieces had evolved from practical commerce into collectible novelties and souvenir items. The octagonal format, originally adopted to distinguish private issues from official federal coinage, became a defining visual characteristic of the California fractional gold tradition. Half dollar octagonal pieces in this period typically feature Liberty head, Indian head, or wreath designs struck by San Francisco workshops that continued production even after the economic necessity for fractional gold coins had largely passed. A notable auction result of $21,000 in MS65 grade at Kagin's demonstrates the premium that gem-quality examples command from specialized collectors. The BG-901 to BG-999 range represents one of the larger groupings within the Breen-Gillio system, reflecting the diversity of die varieties produced by multiple makers during the later period. Collectors pursuing this segment of the fractional gold series benefit from the relative availability of Period 2 pieces compared to their scarcer Period 1 counterparts, though individual BG numbers within this range vary significantly in rarity from relatively obtainable to genuinely elusive.
