San Francisco is preparing to relive its most famous era of fortune-seeking. For the third consecutive year, Witter Coin is launching a city-wide treasure hunt, offering participants the chance to find rare historical currency with a total prize pool exceeding $50,000.
The Grand Prize: The 1851 Humbert “Slug”
The centerpiece of this hunt is a legendary piece of numismatic history: an 1851 Humbert “Slug.” Valued at approximately $25,000, this rare artifact is not a standard piece of U.S. circulating currency, but rather a gold ingot minted by the official United States Assay Office of Gold.
Key features of the Humbert Slug include:
– Unique Design: An octagonal shape featuring a bald eagle perched atop a boulder.
– High Gold Content: It contains 2.5 ounces of gold, making it one of the largest denominations of its kind.
– Historical Significance: Minted by assayer Augustus Humbert, these pieces were essential during the chaotic early days of the California Gold Rush when standardized currency was scarce.
Connecting History to the Present
The hunt is more than just a game; it is a nod to the foundational identity of San Francisco. As Seth Chandler, CEO of Witter Gold, noted, the event aims to revive the “spirit” of the city—a place fundamentally shaped by the pursuit of wealth.
The scale of this transformation is best understood through the city’s rapid evolution:
– Pre-Gold Rush: In 1847, San Francisco was a small settlement with fewer than 470 residents.
– The Explosion: By 1849, the population had surged to over 25,000 as “treasure seekers” flooded the region.
– Legacy: This massive influx of people transformed a remote territory into a global economic hub, a legacy that continues to define the Bay Area today.
How the Hunt Works
The scavenger hunt is designed to be accessible to the public without disrupting the city’s daily life. Participants will be searching for the grand prize slug alongside nine other historic collectible currency pieces.
Event Details:
– Date: Clues will be released hourly on Saturday, April 25.
– Method: Clues will be posted via Instagram to guide hunters toward “iconic San Francisco neighborhoods.”
– Rules: To ensure safety and respect for the community, organizers have strictly prohibited any digging or trespassing to retrieve the prizes.
“We wanted to create something that brings that spirit back. Something real, tangible, and rooted in San Francisco’s history.” — Seth Chandler, Witter Gold CEO
Conclusion
By blending modern social media engagement with deep historical roots, this event offers residents and tourists a unique way to interact with San Francisco’s storied past. It transforms the city itself into a living museum, where history can be discovered one clue at a time.
