The Tiffany 2465 3862 mark appears on sterling silver pieces produced by Tiffany & Co., a leader in American luxury silver since the 19th century. This mark includes two pattern or design numbers—“2465” and “3862”—which were used by Tiffany to catalog specific forms, styles, or production batches. These numbers aid in identifying the exact piece, confirming its authenticity, and placing it within the brand’s production timeline. Multiple numbers often indicate a particular combination of form and variation, such as a base model with a unique decorative element. For collectors and appraisers, the Tiffany 2465 3862 mark is a key reference point for determining origin, rarity, and value.
