1939 Golden Gate International Exposition souvenir clip

This appears to be a commemorative spring-action clip or holder, possibly intended for a desk accessory or as a money clip. The item is constructed from two primary metal components: a silver-toned metal body and a circular brass-colored medallion. The medallion bears the inscription '1939 GOLDEN GATE INTERNATIONAL EXPOSITION' around the perimeter, with 'SAN FRANCISCO' and a depiction of the Tower of the Sun architectural landmark in the center. The silver-toned housing is a rectangular folded metal frame, while the spring mechanism consists of a large, circular tension ring designed to grip objects. In terms of condition, the piece shows surface wear consistent with age, including mild tarnish on the brass medallion and small scuffs on the polished silver-toned metal parts. The rivets and construction are consistent with mass-produced souvenirs of the mid-20th century. While the markings are clearly legible and refer to the 1939 World's Fair, the absence of a distinct manufacturer’s mark means the provenance is based on the visible event-specific text and imagery. This item serves as a piece of 'Exposition' or 'World's Fair' memorabilia.

Based on my examination of the images provided, this item appears to be a commemorative spring-tension clip or money clip produced for the 1939 Golden Gate International Exposition. The medallion bears a design and inscription consistent with motifs associated with the San Francisco World’s Fair of that era, specifically featuring the Tower of the Sun. From what I can see, the construction utilizes mixed non-precious metals—likely a nickel-plated steel or brass alloy with a stamped brass or bronze-finished insert. While the design is historically representative, the lack of a manufacturer’s hallmark means I cannot verify the exact maker through a photograph. The value estimate is predicated on the hypothesis that this is a souvenir from the period. Items of this type are generally sought after by World’s Fair and Exposition collectors. The current market for such mid-century memorabilia remains stable for pieces with clear legibility and intact spring mechanisms, though value is limited by the mass-produced nature of the object. Surface wear and mild oxidation visible in the photo are consistent with age and do not significantly detract from its appeal as a display piece, though any evidence of modern reproduction would reduce the value to a nominal $5–$10 range. To confirm this as a period-correct artifact, an in-person physical inspection is required to assess the weight, metallic composition, and the specific patina of the rivets. The stated value assumes the item is an artifact from 1939; if it were a later-dated souvenir or a modern replica 'in the style of' the exposition, the market demand would be considerably lower.
