The Gorham Athenic Sterling DFO mark appears on sterling silver pieces crafted in the Athenic pattern by the Gorham Manufacturing Company, one of America's leading silversmiths. The word “Sterling” confirms the piece is made of 92.5% pure silver, while “Athenic” refers to a specific design line, likely influenced by classical Greek motifs, aligning with Gorham’s tradition of historically inspired artistry. The letters DFO are likely the initials of the silversmith, chaser, or finisher involved in the production of the piece—a practice often seen in higher-end or custom Gorham silver. This mark represents a collectible and finely crafted piece from Gorham's diverse design catalog.
