The Gorham Coin mark appears on silver pieces produced by Gorham during the early to mid-19th century, before the adoption of the sterling silver standard in the United States. "Coin" indicates the item is made from coin silver, typically around 90% pure silver, derived from melted coins. This mark reflects Gorham’s earliest manufacturing era, when the company was producing handcrafted flatware and hollowware in Providence, Rhode Island. Items bearing the Gorham Coin mark are considered highly collectible for their age, craftsmanship, and connection to Gorham’s formative years as a leading American silversmith.
