The Gorham 325-1000 Fine 102 Spaulding & Co. Chicago mark appears on high-quality silver pieces produced by the Gorham Manufacturing Company and retailed by Spaulding & Co., a prestigious Chicago-based jeweler and luxury goods retailer. The "325-1000 Fine" silver purity mark indicates a higher-than-standard silver content—32.5% more pure silver than sterling, or 97.5% silver, which was sometimes used for special commissions or luxury pieces. The number 102 likely refers to a pattern or inventory number. This mark signifies not only Gorham’s exceptional craftsmanship but also a collaboration with one of America’s elite retailers, making such pieces especially desirable to collectors.
