1915 PANAMA-PACIFIC $50 OCTAGONAL TRIBUTE – 1 TROY OUNCE .9999 FINE GOLD – 30MM (TOTAL MINTAGE: 100)

Description:

One of the most extraordinary designs in American numismatic history, honored in one full troy ounce of .9999 fine gold.

Created for the 1915 Panama-Pacific International Exposition in San Francisco, the original $50 Octagonal gold piece occupies a unique place in United States coinage. Designed by celebrated American sculptor Robert Ingersoll Aitken, it was the first—and remains the only—octagonal coin ever officially issued by the United States Mint.

This magnificent tribute captures Aitken’s celebrated design within an octagonal frame at the center of a 30mm round. The obverse features Minerva, the Roman goddess of wisdom, skill, and disciplined strength. She wears a crested helmet pushed back upon her head, symbolizing peaceful intentions rather than aggression. The Roman numeral date MCMXV appears upon her shield, while the inscriptions “UNITED STATES OF AMERICA,” “IN GOD WE TRUST,” and “FIFTY DOLLARS” preserve the character of the historic original.

The reverse depicts Minerva’s sacred owl perched upon a branch of ponderosa pine, surrounded by pinecones. The owl represents wisdom and watchfulness, while the surrounding octagonal border recalls the enormous private gold “slugs” associated with the California Gold Rush. The original inscriptions “PANAMA-PACIFIC EXPOSITION,” “SAN FRANCISCO,” and “E PLURIBUS UNUM” complete the central tribute.

The surrounding field records the essential history of the original masterpiece. The obverse identifies the 1915 Panama-Pacific $50 and its sculptor, Robert Aitken, while the reverse notes the remarkably small original distribution of only 645 pieces.

Struck in-house by Intaglio Mint from one full troy ounce of .9999 fine gold, this exceptional 30mm tribute is limited to a mintage of only 100 individually numbered pieces. It offers collectors the opportunity to own a substantial pure-gold homage to an original coin that has become one of the greatest rarities in American numismatics.
