This specific numismatic and advertising history forms the backbone of several major sales occurring across the American Midwest over the next 72 hours. From the agricultural hubs of Indiana to the specialized galleries of Illinois, the upcoming auction calendar emphasizes provenance and material authenticity over mere novelty.

The Rodney & Susan Wilson Coca-Cola Collection
Auction Hawk reports that the Rodney and Susan Wilson collection was assembled over four decades with a focus on period correctness and original lithography. The sale is particularly notable for its straight-sided Coca-Cola bottles, representing regional bottlers from the 1905–1915 era. These vessels provide a physical timeline of the brand’s expansion before the standardization of the glass contour bottle. Beyond glass, the collection includes early tin thermometers, figural clocks, and point-of-sale restaurant signage that once defined the neighborhood soda fountain. The Wilsons, long-standing members of the Michigan Coca-Cola Collectors Club, prioritized items with honest wear and historical integrity, making this a significant event for those tracking the market for early American advertising. The full catalog is available via Holler & Hammer.
